Mom, dad, and I walked out from the car holding on to each other's arms.  The air was calm and the trees gently swayed around us. A cool wind sent a shiver down my spine as I took in the unfamiliar scenery. The cabin was truly beautiful, made entirely of wood. But it is still odd, this is my home. 

Two figures were standing on the porch, one of them holding someone. Mom and Dad already told me about Morgan, but I still can't wrap my head around it. 

Five years. 

Little sister. 

"Mom? Dad? Petey?" A hoarse voice says from the porch. I almost cry at hearing the usually annoying nickname because it brings so much comfort and familiarity in a time where nothing is the same. 

The three of us break into a run, mounting up the steps to the cabin. I wrap my arms around Harley and bury my face into his shirt. "Har-Harls," I sob, gripping on to him tighter. I feel two sets of arms wrap around us and a small hand on my back. 

"I missed you all," Dad says from behind me. 

After a while, we let go of each other and I move to give Uncle Happy a hug, "I'm happy your back, Peter," He says his voice barely above a whisper. 

...

Harls:  Hurry up, Peter! They are almost at our house!

Me: Coming!

I say goodbye to Ned and close my locker, running through the school doors, down a block to Harley's car. I open the door and sit down quickly buckling my seatbelt and closing the door at the same time. 

"Is everybody coming?" I say with excitement. 

"Clint and his family, Natasha, Steve, Bucky, Bruce, and Thor." Harley turns down the music ever so slightly so I can hear him. 

"What about Loki?" 

"I think he is helping Valkryie with something but is going to come soon."  

Neither of us says anything for a while, just listening to the music pump through the speakers. 

"How was your day?" I ask. 

"Fine, you?" 

I just shrug and look down at my fingers picking at my already short nails. 

"Peter," Harley sighs looking over at me. I sigh at the use of my real name and not my nickname. 

"Mr. Phalin is stupid and so is English," I mutter folding my legs under me somewhat difficultly in the car seat. 

Harley looks over at me for a second before responding, "I told you I can help you with the essay."

"Yeah but-"

Harley glares at me and I know I should just stop talking because nothing is helping me with my case. 

...

"Uncle Bucky! Come here!" Morgan shrieks running up to the man and grabbing his metal arm, tugging him towards the fort Harley and I are inside of. 

Bucky dramatically pretends to fight against Morgan and calls for 'Stevie' to come to help him making the three of us giggle when Steve smirks and turns towards Natasha joining her and Pepper's conversation. 

Morgan crawls into Bucky's lap when she has him seated in the epic fort of blankets we created. 

"Morgan wants you to tell a story of the 40s," Harley says stretching his legs out from the bent position they were in. 

Bucky begins to tell us a story about the time he and Steve got kicked out of the fair for being too annoying to others around them. It was quite a funny story that had Morgan in tears. 

... 

 After another hour the four of s were sitting on the couch listening to Steve and Tony jokingly fighting with Thor about which pop-tart is better. Except for Thor, it wasn't very joking, his face was red with anger, and I was only a little scared that lighting was going to shoot out of his hands at any moment. 

"Ok boys," Natasha said with authority stopping their fight, "I think its time for us to go out." Often times when we all get together after a few hours the adults go out to the bars and Clint and his family head home because they have a long ways to go. 

"Harley, you're in charge, make sure Morgan gets to bed at 7:45, and don't forget you all have school tomorrow," Pepper says making Morgan and I protest about all the reasons that Harley shouldn't be in charge. 

Harley just smirks at me, "Sorry Petey," I roll my eyes at him and hug everyone goodbye before returning to the couch. 

...

 Nine o'clock rolls around and Harley and I are sitting on the couch, him helping me write my essay. 

A tingling erupts in the base of my neck and I jump slightly looking around, Harley looks up at me in confusion, "Spidey sense... let's go check on Morgan." I whisper, standing up from the couch shoving my computer from my lap. Harley jumps up and follows close behind me. 

I push the door open to her room and walk out the bedside, "Petey? Harls?" She whispers peaking her eye open.

There is a noise from downstairs and all of our eyes widen in fear. 

"W-what's hap-happening," Morgan whimpers pulling the covers tighter around herself. 

"Harley, stay with Morgan and call Dad," I say in a firm voice, not leaving any room for discussion and turning to leave the room and work my way down the stairs into the living room. 

Halfway down the stairs, a sharp sting erupts in my arms and the world around me spins, tripping over my own feet I fall down the stairs landing in a heap on the ground. 

"I got the kid, let's go before they get home." 

I can't move, I can't do anything. An arm wraps around my body and I can't do anything. 

Come on Peter! Do something! What's happening to me! Someone help! Help me! Harls? MOm? Dad? Morgan? Oh god... what's happening? Please... Please help me... Please. Oh god! No, what's going on... no please no!

"LET GO OF MY LITTLE BROTHER!" 

And that's the last thing I hear.
