Chapter 1: A Blast from the Past

Kara heard someone approaching and turned to see who it was. Alex, Winn, J'onn, and Mon-El turned to see what had distracted Supergirl from the briefing they were having at the DEO. Kara took a few steps forward towards the new arrival. A few DEO agents drew their weapons and before Kara could speak, the woman who stood before them all spoke.

"I mean no harm. I am Diana, Princess of Themyscira, Daughter of Hippolyta, Queen of the Amazons. I am here to help. Kal-El sent me to help Supergirl."

Kara froze for a second. Diana? She knew a Diana but, this woman standing before her couldn't be her Diana. Could it? Kara would recognize that voice and accent from anywhere. It was intoxicating. Kara moved forward, looked at the woman and said, "Diana?" Diana really looked at Supergirl, she took in her facial features and she gasped, "Kara." Diana knew that Clark's cousin was Supergirl and her name was Kara but, she never expected it to be her Kara. The Kara she dated for a year and who suddenly left her and broke her heart. Diana immediately stiffened, she could address her feelings later. They had a war to win against the Daxamites and an alien invasion to stop. She didn't have time to be concerned with the heartache that the woman before her caused when left 10 months ago, without a real explanation. Diana responded coolly, "Hi Kara. It's nice to see you again. Kal-El thought you could use some assistance. He thought since you defeated him in battle before and I have different powers, I could be of use. They won't be expecting me where they might expect Kal-El."

J'onn stepped forward. He was able to read minds but, for some reason he couldn't read Wonder Woman's mind although he knew she was who she said she was as he had met with before. However, he could read Kara's and knew that there was a history between the two of them and didn't want it to get awkward since Kara and Mon-El were both present. "Hi Diana, I'm Director Henshaw also known as J'onn Jonzz. Director of the DEO. Thank you for coming to help. We were just holding a briefing on the situation if you would like to join us."

Diana nodded and responded, "Nice to see you again J'onn." Diana stepped forward to the console that everyone was standing around. Alex knew she was missing something. How did Kara know Diana? It seemed like she knew a Diana but, she didn't know that Diana was Wonder Woman and Wonder Woman didn't know Supergirl was Kara. She would ask Kara about this later. She looked over at Kara and she seemed a bit uneasy. But, she didn't stop J'onn from accepting her assistance.

J'onn cleared his throat and continued with the briefing, "Lena is working on a device that will disperse lead that should not be harmful to humans but, will be to the Daxamites. Using this device is our last resort. Supergirl will fight Rhea and try to force the Daxamites to retreat."

Diana was confused, if this device would force the Daxamites to retreat and wouldn't harm the humans then why wouldn't they use the device first? "I'm sorry. I don't understand. If you have this device and it can stop the bloodshed of humans and end the war. Then why is it not the first option?"

Diana looked around the table and everyone was shifting uncomfortably. However, Mon-El spoke, "It's because I am Daxamite and my parents came here for me but, I do not wish to return to their way of life. Also, because I love Kara and we are together and we do not wish to be separated unless it is absolutely necessary." Diana looked from Mon-El to Kara in confusion and not because Kara was with a man but, because they would risk innocent lives for selfish reasons. That is not what a hero does.

Diana felt herself getting angry, "Those are the dumbest reasons I have ever heard of. We are at war and the two of you would be so selfish. You two would put yourselves and your needs above thousands? That is not what heroes do." Diana couldn't believe what was hearing. Kara heard what Diana had said and whirled around to face her, "I put my life on the line every day to protect National City. Mon-El and I are together. He is trying to be better than his people and trying to be a hero. We protect our own."

Diana scoffed, "Kara let's get real you aren't putting your life on the line every day. The only thing that can kill you is Kryptonite and it isn't that much left on Earth. You aren't battling someone with Kryptonite every day. These humans are putting their lives on the line every day when they go into battle. Oh, and I don't even know what that means teaching someone to be a hero. Either they have it or they don't. You can train them but, their virtues and morals are either there or they aren't. I didn't know you were such an idiot." Alex stepped in, "Wait a minute. Who do you think you are to speak to my sister like that?"

Diana raised her eyebrow and looked at Kara, "Should I tell them, or will you?" Kara looked at Diana, "What you speak of doesn't matter. If you want to help fine, then help. But, this is my city and we are doing it my way." Diana stepped forward to Kara and said, "Oh, but it does matter. You think you are the only that has ever fell in love and lost someone in battle. In World War I, I had just come to man's land and I had to fight Ares, God of War. He was responsible for all of the death and destruction. I met a human named Steve. We fell in love. He blew himself up on a plane to save thousands. I wanted it to be me because I would have survived but, he knew that I had to fight Ares and save the world. That is a true hero. That is what heroes do. They don't let others die for them because they don't want to make the hard choice. It's not about you loving him, it's about doing the right thing." Everyone was quiet, they knew Diana had a point. But, no one had been brave even to speak their mind and tell Kara that. This fight was bigger than Kara and Mon-El.

Kara did the one thing no one expected, she stepped forward and punched Diana in the face. However, no one expected Diana to barely move. Her face moved slightly to the side from the impact of the punch. But, other than that she stood firmly in her spot. "Kara, I am not going to fight you. It is pointless and most of all it won't end well for you and I don't want to hurt you. Since I am not needed in this fight I will take my leave. I only came because your cousin and I are friends. I definitely, wouldn't have come if I knew it was you and you were only in this position because you refuse to do what is right."

At this point everyone was staring at both of the women. Trying to understand how they knew each other. Winn was speechless because, Wonder Woman was standing right in front of him and she was beautiful. More beautiful than any pictures or videos he had seen, they didn't do her justice. He always thought she was attractive but, seeing her in person was definitely surreal. He knew James would be upset that he missed this and probably Lena too. Alex didn't know how to process what was happening because she didn't understand the hostility the women had towards each other. J'onn's face was unreadable, you were never able to tell what he was thinking or how he was feeling. Mon-El looked uncomfortable, he didn't know whether he should intervene or let them continue arguing.

Kara spoke, "Fine. Running away and hiding that's your thing isn't it. Oh yeah, I've heard about you and Steve from my cousin. You mourned him for 100 years. You disappeared for 100 years and yet you lecture me about what I should do?"

Everyone took a couple of steps back because they knew that was the wrong thing to say. J'onn had already cleared the floor of all other personnel because he expected this to happen. Diana's eye were blazing at this point. She was livid. How dare Kara speak to her about Steve? How dare she speak to her about running away? "So, you do want to do this in front of everyone then? We were together for a year Kara. I never knew you were Supergirl. I woke up one day and you were gone. All you left me was a note that said, Goodbye. Yet, you lecture me about running away? About hiding? And don't you dare speak of Steve. I left my home to defend the humans. I have stayed hidden among them for 100 years. Just because you didn't hear of me helping didn't mean I wasn't." Alex's jaw dropped at the revelation that Kara and Diana had dated for a year and she knew nothing about it. Winn slapped himself to make sure that he wasn't dreaming this conversation. Mon-El was furious Kara never told him that she liked women before because he thought maybe she would have been down for threesomes. J'onn stood there stoically. Lena had walked in at some point during the confrontation and was just standing there taking everything in. She didn't dare move. This was better than her guilty pleasure of watching reality TV.

Diana punched Kara and she flew back into a wall. Kara was angry, and she used her super-speed to try to surprise Diana and although she was slightly faster than Diana. Diana was a warrior and she fought back. Kara flew up and tried to use her laser beams on Diana but, she blocked the attack with her bracelets. Diana was hovering in the air with Kara and they rushed each other, and their clash sounded like a big BOOM. J'onn had enough of this and changed into his Martian self and tried to telepathically connect with the women. This time he got through to Diana and told them, "Enough. We have bigger problems than a lovers quarrel and you two are destroying government property." They both stopped fighting and Diana spoke, "I apologize J'onn. I will be taking my leave. If you all really need assistance, then you know how to contact me." With that Diana took her leave.

Mon-El approached Kara angrily, "What the hell was that?"

"I really don't want to talk about it. She's gone. We have our plan. Let's stick to it." Kara replied.

Lena tentatively approached the group, "I was coming to tell you all that the device was ready. What I walked into was rather interesting."

Winn responded slightly amused, "Very interesting indeed."

Alex sighed, "I don't know what the hell that was but, you have some explaining to do later. Oh, and if I were you I wouldn't try to fight her again. She could have kicked your ass. She took it easy on you."

Kara huffed, "She can't beat me. Who's to say I wasn't taking it easy on her?"

Lena responded, "Kara, you know we all love you. But, she definitely could have kicked your ass."

Kara raised an eyebrow, "Wait. Did you just call me Kara?"

"Kara, I have had my suspicions for a while. But, that whole scene just put it together. Don't worry. Your secret is safe."

Kara hugged Lena, "Rao, I thought you were going to be upset with me because I didn't tell you. Don't think it wasn't because I didn't trust you. I just needed a space where I could just be Kara."

Lena shook her head, "No worries. I understand."

J'onn said to everyone, "Lena brought the device. Winn and Alex, can you go to the lab with her and have her show you two how it works. Mon-El and Supergirl we will let you know when we are ready to move."

Lena, Winn, and Alex walked to the lab. Winn was the first to speak, "Can you guys believe that? Kara and Wonder Woman and they didn't know about each other secret identities? When did this happen? How did we not know?"

Lena responded, "Well, she did mention in passing before about an ex before but, she never said it was a she or gave any details. I didn't press her because it didn't seem like a topic she really wanted to discuss in detail."

"Well, she never mentioned an ex-girlfriend to me and she knew I had a hard time coming out." Alex replied.

Lena looked at her and said, "That might be why she didn't mention it. It was something she never accepted for herself. Diana said she just left a note and it only said Goodbye. She didn't give a reason. She didn't talk to her or anything. I mean did you see her? Who leaves a woman like that unless they have some issues they are dealing with themselves."

Winn spoke-up, "Yeah, that has to be it. Because I wouldn't ever leave a woman like that. The accent, the face, those legs, not to mention the Wonder Woman costume." Lena and Alex chuckled.

"Well, apparently she didn't know she was Wonder Woman. We should ask her for drinks tonight. To help her decompress. Well, honestly just to get the details on what the hell happened." Lena said.

Alex and Winn nodded in agreement.
