Steve/Captain America's POV

I still wasn't sure about Tony's decision to take in Phoenix and her brother. Didn't he realise the danger that would put them in? But this wasn't the time to think of such things, we were about to go send Thor and Loki off to Asgard where Loki would face his trial.

When I arrived, I saw Loki wearing a face guard and looking rather disgruntled. I climbed out of my car and walked over to stand beside Thor before scanning my surroundings. Call me paranoid but I felt like we were being watched, and I wasn't sure if the person who was watching us was on our side.

I was deep in thought about who it could be when I saw a flash of sea-green on a nearby roof. I was about to go investigate when I heard the rest of my team arrive. I nodded at them, about to properly greet them, when I caught a glimpse of Thor. He was anxiously glancing around, as if expecting someone to show up and interrupt our little send-off.

I walked over to him, and was about to question him when I heard someone clear their throat. I whirled around to see a masked girl, hovering in midair and casually holding a strange-looking sceptre. She had long white hair and was dressed in different shades of blue.

"You know, it's polite to greet guests."

Her voice was clear and she had an American accent. She glanced around at us, and sighed.

"No? Well, might as well get down to business. This guy," she gestured to Loki,"is being mind controlled."

We all stared blankly at her and she sighed.

"See how his eyes are a pale blue, well they're meant to be green, that's a symptom of a mind control spell. This one is very strong and subtle. Besides if he was actually in control he would have been a lot harder to beat. I'd recommend getting him to a seidr user in Asgard, possibly my grandmother, Freda, though warn them that it'll be hard to break."

She directed most of this to Thor. She glanced around at us, and seeing that none of us were asking any questions, she grasped her sceptre and was about to fly away before I grabbed her wrist. She turned her icy blue gaze to me. I blurted out the first thing that came to mind.

"What should we call you?"

She pondered this question for a few moments before answering.

"Glacier. Call me Glacier."

We were all waiting in the living room, wearing 'normal' clothes. Today was the day Stark would bring Phoenix and her brother, Hercules, to the Tower.

It had been two days since we found out about Glacier. We had talked for hours about what to do, before agreeing to tell Fury. He told us to detain her and bring her in for questioning next time we saw her. Thor was still on Asgard, waiting for Loki's trial.

Thor had been ecstatic when Glacier told him Loki was being mind-controlled, but I didn't quite trust her. This could all be an elaborate plan to free Loki. She was his daughter, she could be helping him. I didn't want to judge her on her heritage but I had to look at all the possibilities.

I was startled out of my thoughts by the elevator doors opening. Tony and a teenaged boy walked out, with Phoenix trailing behind them, occasionally glancing nervously at the boy, as if worried he'd attack her.

The boy, who looked to be around 18, was tall and looked strong, he had murky green eyes and wild, chocolate brown hair that almost reached his shoulders. He had a light tan and was pretty good-looking. Phoenix was much the same as the last time I had seen her but had tidied herself up a bit and braided her hair.

Tony stepped forward with a grin and gestured to the two kids. "This is Hercules and Phoenix, who prefers to go by Nix. They already know who you are. Pepper will be here in a few minutes and-"

Tony was interrupted by JARVIS, who was alerting us to an attack in Central Park. Tony quickly showed the kids to their rooms as we suited up. We were by the Quin Jet within 5 minutes.

"Avengers Assemble."

Phoenix's POV

I couldn't believe my luck. Two minutes in the Avengers' Tower and there was already an attack on the city. Living with the Avengers and keeping my secret identity a secret was already turning out to be difficult.

I sighed as I slipped into my new room. It was really big with a big blue bed, three deep blue walls, a window that took up an entire wall, an oak wardrobe and desk and an ensuite bathroom.

I quickly put up a glamour around the bed so that I appeared to be sleeping. Then I teleported to Central Park, while dropping the glamour I kept to hide my true appearance, so that I could scope out the battlefield.

The only reason I hid my appearance was so that no one would look twice at me, I couldn't allow anyone to figure out my heritage, I would be killed.

As I looked around, I saw these humanoid robots destroying the park and terrorising civilians. I felt the anger coursing through my veins, this was the work of someone who enjoyed making people feel helpless, enjoyed destroying things simply because they wanted something.

I hate those kinds of people.

I was about to make my appearance as Glacier when someone grabbed my wrist. I whirled around to see Captain America. I quickly tried to appear as helpless and afraid.

"You should get out of here ma'am, let the professionals handle this."

I nodded and hurried away, slipping into an alleyway where I could transform into Glacier and join in on the fight. I quickly put up my glamour for Glacier and summoned my sceptre.

Looking around for anyone who could have possibly seen me, I teleported to the centre of the battlefield.

Let the fight begin.

Steve/Captain America's POV

I couldn't get that strange girl out of my head. She would be considered very beautiful with her long dark hair and bright green eyes but that wasn't the reason I remembered her.

The anger on her face as she turned around to look at me was disturbing. The mask of helplessness and confusion that replaced that anger, only disturbed me more. Not to mention she seemed vaguely familiar.

Why would she hide her anger?

Why did she seem kind of familiar?

Did I know her?

Have I seen her before?

I shook my head, now wasn't the time to think about strange girls. I had a battle to think about. As I fought my way to the centre of the battlefield, I saw Glacier appear with a faint smirk on her face.

Our chance to capture her had come.
