"So, where's the shawarma place?" I asked Tony.

"At this address." Tony gave me a slip of paper with the address of the restaurant. "Meet us there when we call you. We're going to check the place out to see if it's still there or if it's been completely destroyed."

"Why can't I come?"

"You have to stay here with Loki until some Shield agents come to guard him," Tony explained.

"Okay?" I said, not so sure if this was the best plan Tony had in mind.

"We'll see you later," Natasha said.

"See ya."

Everyone left the tower, except for me and Loki who was given special handcuffs by Thor.

Neither of us spoke. Loki not being able to and me not really knowing exactly what to say.

About half an hour later, a quinjet landed on Tony's helipad and out came Phil and a few other agents.

"We'll take it from here," Phil said, motioning for the agents to get Loki.

"Hey, Sophie, turns out the shawarma place is still here with minimal damage. We'll see you here in a few. Stark out," Tony said over the earpiece.

"Need a ride?" Phil asked.

"Yeah, it's..."

"Don't worry, I know where it is." Phil turned to the agents guarding Loki. "Stand guard until we get back and keep me posted if anything happens."

We took the elevator, which was still working, down and walked to the shawarma joint.

"Happy Birthday!" the Avengers yelled once I opened the door.

I looked around in surprise and saw a cake and some presents on a nearby table. Everyone, except for Tony, Bruce and Phil, was still in their dusty suits, and I could see towards the back of the shop that the workers were still cleaning the place up.

"I understand this isn't the ideal place for a birthday party, but..." Bruce started to say.

"It's perfect," I finished. "But how did you... Wait let me guess. My ID card."

"Bingo," Tony said and we all laughed.

After we ate, we had cake. Then it was time for the presents.

Thor's present was a trip to Asgard whenever I would be able to return to this world.

Bruce's present was to teach me about gamma radiation.

Natasha promised to teach me some of her martial arts and Clint promised to teach me some of his archery skills. Clint even said he would give me one of his collapsible bows.

Steve's gift was a sweatshirt with his shield logo on it, which I've always wanted to get.

Next it was Tony's gift, which was one of his transparent phones.

"Don't worry, I'll teach you how to use it later," Tony reassured.

Phil said that my gift will have to wait until we get back to the Helicarrier.

"These are all awesome presents, but how would I get back to this world? How would even get back to my world?"

"Those are some interesting questions, Miss Spacer."

Everyone turned around to Nick Fury, who just walked in through the doors.

"I've been putting some thought into this hunch of mine and I still stand by that hunch to be true. As you may or may not know, The Keeper has the ability to transport people to other dimensions or universes. It's similar to that of the Gatekeeper in Asgard. Although we don't have the technology to do so, the next best thing to transport people... Is a key."

Nick pulled out a key and gave it to me. Everyone was just as confused as I was until I remembered that I had brought my house key with me. I don't really know why, but I had it.

I took it out and held one key in each hand. Then I put both keys in one hand when they began to glow. The harder I pressed on the keys, the bigger the glow would get. I pressed on the keys until they joined together to make one new thing.

The final key was covered in a black coating with the Shield logo on it.

"Welcome to the Avengers, Keeper," Fury said with a smile.

I couldn't help but smile as we all came together in a group hug.

At the Helicarrier

"Here's your present," Phil said, sliding a wrapped box across the table.

Inside the present was a backpack, but with no zippers.

"It's a backpack! But with no zippers..."

"It's more than just a backpack," Phil explained. "It's a backpack that only you can open. Here, put your hand on the front."

The backpack scanned my hand successfully and read: Handprint found. Sophie Spacer.

"Now think of this backpack as like a touchscreen."

I slid my finger across the backpack the same way I did to unlock my iPod, in which a pocket formed exactly where I had slid my finger.

"Whoa, that it so cool," I told Phil.

"Yeah, I had a little design input and I heard about Stark going through your stuff."

"How do I close it?"

"Just slide back. This backpack is also bulletproof, fireproof, waterproof, shockproof, pretty much indestructible. It also has a camouflage setting where you can change the design of the backpack anytime you want."

"Sweet! Thanks, Phil!"

"No problem. Now, are you ready to go back?"

"Not really... It was so fun being here and meeting all of you. Can I at least stay for a few more days?"

"Sorry Soph, but you leave Hawaii tomorrow. And it would be suspicious if you didn't return with the rest of your classmates."

"Right... What did you tell my teachers about me not being there, anyways?"

"It's a long story. Just go with whatever they say."

"Got it. I'll see you next time," I said with a smile.

I put the key into a keyhole and turned it until I heard a click. I opened the door and walked through, back to the condo in Hawaii.

So, that's the final chapter of The Keeper. I hope you all enjoyed this story and tell me if you want more! Special thanks to all those who reviewed, favorited/followed this story, and everyone who stayed to the very end! You guys are great!
