Avengers little sister

Rescue

Tony POV:

"Mister Stark there is no sign of Stacey anywhere." JARVIS called out to everyone through our ear pieces.
"Where could she be?" Natasha asked.
"Hold up, I see someone." I called out through the ear piece, indicating to Steve, my 'partner' while looking, to follow me.
"What, what is it?" Clint asked.

I crouched down to the glistening object on the ground to see it was Staceys phone. I picked it up as Steve looked at it in shock. The screen was not smashed but there was some scratches on the back of it.

"We found her phone." Steve said into his earpiece.
"That's not helpful." Sam sighed into his earpiece.
Just then we heard a scream from the distance.
"You all hear that?" Clint asked.
"Yep." Natasha said.
"Everyone go to the noise, go go go." Steve ordered as we ran off.

I covered my face again and took off into the air, just  above Steve, as he ran in the direction of the scream.

Stacey POV:

"I'll ask again, where is the 'avengers' associated?" Ultron asked, putting air quotes around avengers as he got a knife from his pocket.
Wanda and Pietro were gone to fight whoever was above us. I could here it from above while Ultron came down to me.
"I will never tell you no matter what you do." I spat at him.

Ultron raised his knife and rested the tip against my cheek. He then dragged it down my face to my jaw, not hard enough to cut into the flesh, but hard but I still whimpered as I tried to back away, but he reached up and clasped the base of my neck to hold me there. 

"I can do this all day." He taunted, not moving the knife.
"well then you'll be annoyed by the end because I ain't telling you noting." I said, whimpering as he dug the knife into my cheek.
"But you will." He said, smirking like an idiot.

He undid the binds keeping me in the chair before throwing me across the room. I gasped in pain as I hit my back against the curve of the wall. Ultron came over to me and brought  his fist up before pelting it down into my rib cage. The breath was knocked out of me from the blow and I doubled over to catch my breath as he pushed back up to full height. He then redid his knife and held it over his head. I glanced up at him and he just smirked. There was a stinging pain in my leg and I screamed as  tears slipped down my cheeks. He went down with the knife again and I blocked my face while closing my eyes. 

I opened them slightly when noting came to see Steve and the others attacking Ultron. Soon they had him down on the ground, weakened and looked over towards me. Steve rushed over and checked me over. He went to pick me up causing me to cry out.

"Shh, your ok, I've got ya." He sad, adjusting me in his arms so he could carry me.
"We need to get her back." Natasha said, looking at my leg wound.
"Steve bring her back. Meet you there." Tony said before taking off.

I looked at Nat who shrugged before we all left the building. That was the last I knew before I blacked out, forgetting about my meeting of my 'dead' older siblings.
