Italic=Thoughts

Recap: "Thank You," Hank replied. "Now go catch up to Supergirl. If you can," and with that Hank left Harry at the entrance to the DEO. Was that a challenge. Harry thought, smiling. This is going to be easy.

Chapter: 3

Harry grinned to himself as he grabbed his broom from his pocket. He hopped onto it as he enlarged it. Harry swooped up into the air until he was above the buildings. He smiled to himself, this was the perfect view. Harry turned his head back and forth listening for the telltale sign of a sonic boom that would reveal the position of Supergirl. After a couple minutes of listening he heard it. The echo of a sonic boom and from the sound it was only a couple blocks away. Harry angled his broom to the West and shot off. Harry swooped around the buildings looking for Supergirl.

After a couple minutes he decided to take a different approach. He shot straight a building before standing up on his broom and jumping off. He twisted in midair and shrunk his broom and summoned it, placing it back in his pocket. As he fell he made sure to look like he was scared. He could see cameras flashing below him and it looked like there was a news van as well.

Back at the DEO

Hank stood watching the news. Someone was falling, and they were falling fast.

"Supergirl do you got this?" He asked Supergirl through the comms.

"of course I do. This will be easy," She replied. Hank watched the news and saw the man coming closer and closer to hitting the ground.

"Supergirl, you better get there quick," Hank said.

"I got it, I got it. Hold your horses," she replied and a second later Hank could see her on the screen. Supergirl shot toward the person which Hank could now see was a man. Supergirl shot toward the man who was about to hit the ground.

"Come on Supergirl," Hank said to himself as Supergirl neared the man. Just as he was about to go splat on the side walk Supergirl caught him.

"Good Job Supergirl," Hank said through the comms. He could see her landing and setting the man on the ground.

"Um, Hank it's Harry," Supergirl said. Hank laughed.

"Well I did tell him to find you. I however didn't expect him to jump off of a building to do so," Hank said. "Supergirl I want you to take him on patrol. Show him the ropes and don't get him killed," Hank could see Supergirl nodding on the camera before she grabbed Harry's arms and shot up.

Harry grinned as he and Supergirl shot into the air.

"Well that was fun!" He said to her.

"You consider almost dying to be fun?" Supergirl asked.

"I would've been fine," Harry said sounding completely confident in himself.

"Right," Supergirl said rolling her eyes. She stopped on top of a building and let go of Harry.

"What are we doing up here?" Harry asked. He looked around; it sure was a nice view.

"Prove it," Supergirl said a slightly mischievous look in her eyes.

"Prove what?" Harry asked.

"Prove that you would've been fine if I hadn't caught you," Supergirl said. Harry grinned which seemed to unnerve her.

"All right," he said before turning and jumping off the building. He heard Supergirl gasp as he fell but Harry ignored her. He spun in midair and pinned his arms to his side. As he was about to hit the ground he pulled out his broom and enlarged it. He carefully landed on it and shot up to the top of the build surprising a stunned Supergirl.

"Were did that come from?" She asked. Harry grinned mysteriously.

"That's for me to now and you to find out. If you have the skill," he said. Supergirl frowned at him.

"Fine. Since you can fly just try and keep up," she said before flying off. Harry grinned before shooting after her. Harry was glad that he had enchanted his broom to go faster than a bullet or else he would have never been able to keep up and even then he had to use apparition to keep up. Well at least this is good practice. Harry thought. Harry's eyes narrowed as Supergirl suddenly stopped causing Harry to almost run into her.

"Why have we stopped?" Harry asked. Supergirl pointed at the street below.

"I want you to handle it," she said. "Do you have a mask?"

"I don't need one," Harry replied before casting a quick glamour on his face and tipping off of his broom. His broom remained floating beside Supergirl has he shot toward the ground. The scene below him was chaotic as the robber pressed a gun against a man's temple. Harry narrowed as he saw the flashing lights of a police cruiser nearing the scene. Harry spun suddenly and let his magic surround himself. Harry was surprised by the sheer amount of magic that he had access to. He flicked his wrist and a small tornado formed below him slowing his descent before he vanished it and dropped the remaining feet to the ground. The thief spun as he heard the thuds of Harry's feet hitting pavement but Harry was a step ahead of him. He apparated behind the robber just as he spun around. Harry's hand came up and flipped the gun out of the robbers hand. The robber spun around again and launched a punch at Harry. Harry sensed it and in a split second the thief was on the ground his hands pinned together with a sticking charm. By the time Harry had taken down the robber Supergirl had gotten over her shock and landed on the ground Harry's broom trailing behind her.

"Hey stop this. What's keeping my hands together. You can't do this," the robber complained struggling.

"Actually," Harry replied, "We can and we just did," he looked at Supergirl.

"We can do that right?" He asked quietly.

"Yes," Supergirl replied.

"Well then let's go," Harry said before hopping on his broom and shooting into the air. He felt the air shift as Supergirl followed him back to the DEO. Harry quickly let Supergirl pull ahead of him so that he could apparate again. He didn't want to give to much away after all. They already seemed to know more than they should. Harry frowned at this thought. Why had he been sent here and how was this world so different from his own. He resolved to find time tomorrow to apparate to Britain and check to see if wizards existed or if he was in an entire different Universe.

Harry pulled himself from his thoughts as he realized that they were at the DEO. Supergirl was looking at him weirdly.

"What?" Harry asked.

"Just wondering how you kept up with me. That thing doesn't seem to fast," she said pointing at his broom.

"I made some... adjustments to it," Harry replied before holding the door open for her. "After you," motioning with his hand for her to go in. She nodded her thanks and stepped inside, followed closely by Harry. Before they got to far inside Alex met up with them. Harry was still slightly weary about her and he knew that she felt the same way.

"Hank wants us to meet down in the prison cells," Alex announced after a couple moments of silence.

"K you take Harry down," Supergirl said. "I'll only be a second," Alex nodded before moving away from Supergirl. Harry followed her as she led him down the familiar hall. Alex held open the door for Harry once they reached the boardroom. He entered to see Hank standing talking to one of his soldiers.

"Activate Alpha 1," Hank said before turning to Harry and Alex.

"Where's Supergirl?" He asked. Harry turned to Alex.

"She went to do something. She should be here soon," Alex told him. Hank nodded before turning to Harry.

"How did the first day go?" He asked.

"It was boring," Harry replied, "We caught one bad guy," Hank nodded.

"That's good," he said as Supergirl entered the room.

"What's good?" She asked.

"Harry was just telling me that you caught a bad guy," Hank told her. She nodded.

"Yah he was good," Supergirl replied.

"Are we going to get started with whatever you wanted us in here for or are we just going to talk about how well Harry did on his first day?" Alex interrupted.

"Right yes. Let's get started," Hank said sitting down. Supergirl and Alex sat down together but Harry remanded standing. Hank looked at him for a second but said nothing.

"We just detected something approaching our planet," Hank started with, "We assume it is a asteroid but we don't know. It could be anything, so I have activated Alpha 1. It is for situations like these so everyone will follow the guide," he handed each of them a set of papers.

"So that is it?" Harry asked.

"No. In case it is an alien life form I need you, Supergirl, and Supergirl I want you to contact Superman, because I need you all on call. Got it?" He said looking at Supergirl.

"Yes I got it," Supergirl said. She must not like this Superman person. Harry thought. Then Hank turned to him.

"This is for you," he said holding out his hand. In it was a small ear piece. Harry took it and placed it in his ear.

"I also have a phone for you," Hank continued holding out an iPhone. Harry took it as well and slid it in his pocket. "The ear piece is blue tooth and is connected to your phone so if you get called you don't have to answer the phone," Harry nodded his understanding.

"Great now that we can contact you if necessary I want you girls to take Harry home and get him settled. He will be staying with you until we get a house set up for him," Hank said looking at the girls sternly leaving no room for negotiations. They nodded.

"Well go then," he said as they didn't move. The girls quickly stood up, nodded to Hank and then left the boardroom. Harry nodded to Hank and then followed them.
