A/N: Honestly, this is just a bit of shameless Morgan and Peter fluff, but I hope you enjoy! I really wanted to touch on the sibling relationship between these two, and I hope I got it right!

Mrs. Stark ends up calling Happy to give them a ride home. They offer to drop me off as well, but I shake my head, saying that I'll swing home. I need a moment or two to myself before I have to answer all of Aunt May's questions.

Wait.

Aunt May. Shoot.

I am nearly to our apartment building when I realize that I haven't called her yet. Not since the last battle with Mysterio, where the three visitors showed up to assist me. I wonder if she's seen the news yet.

Arriving at our building, I pause on the roof. "Karen, can you call Aunt May for me real quick? Thanks."

"Of course Peter. How was your trip?" She tries to make small talk before the call is answered, but before I can respond, May picks up.

"Peter? What's wrong? Are you- Is everything alright? I saw the news, why didn't you call me right away? Do you need to come home? I can get Pepper to send one Tony's suits to pick you up, it's okay. I knew we shouldn't have let you go on this trip!" Her statements are strangely similar to what Pepper said when I called her.

"No!" I'm quick to assure her. "I, um. I'm kinda outside? And I didn't want to just come in and freak you out, so, I thought I'd call? And let you know before I just climb through a window while I'm supposed to be in Europe?" I laugh awkwardly, crawling down the side of the building before entering my room via the window. "So, yeah. Um. I'm kinda in my room now, so Imma just hang up now, yep." I click the red button on the phone screen, then walk into the living room.

"Petey! Momma said you were gonna be gone for a whole week! That's seven days, why are you here already? Oh! Do you wanna help me build my Legos? I'm building a castle!" She has a confused little pout on her face. It's cute.

"Hi Morgie! I just missed you so much! I wanted to come say hi to you, and Momma, and Aunt May! Is that okay with you?" I tweak her nose, giggling when she goes cross-eyes, trying to watch my hand. It's hard not to be happy to see her when she's always so excited to see me.

I can see May watching me from the kitchen, a questioning look on her face. "Hey, I'm gonna go say hi to Aunt May, okay? Keep building the castle, I'll be back in a few minutes, okay?"

She nods, then concentrates on the pieces in front of her, tongue sticking out of the side of her mouth.

"Hey, May." I smile at her sheepishly.

"You, sir, have got some major explaining to do."

I nod. "Okay, so you know how there's this theory, the multiverse? How every choice you make can create an entirely new universe?" She nods. Me and Ned have discussed it with her before. "Turns out it's real, and something happened with the Infinity Stones, allowing portals to open up between them. You saw the news, right?" She nods again, face hard to read. "Okay, so the guy I was fighting, turns out he's some crazy villain from another Earth. Called himself Mysterio, isn't that lame? Anyways, um. Well, four other people kinda sorta-but-not-really came with him, and three of them sorta helped me finally defeat him?"

"Okay, and? Does this have anything to do with why Pepper called me asking me to keep Morgan for a few more hours, or why she called back twenty minutes ago and asked if she could spend the night?"

I flinch. "Sorta?" I rush to get it all out before Aunt May can say anything. "The four other people who came over, are kinda the counterparts of the Black Widow, Captain America, and uh…" I check to make sure Morgan isn't listening. She is. "My mentor? And maybe his son, as well?"

Aunt May rubs her temples. "What? Peter, honey. You know… You know that can't happen, right? That he's gone? I wish he wasn't, but he is, and we can't change that. I'm sorry, Baby. I know you miss him, but don't you think he'd want you to move on? It's been almost six months. It's time, Peter."

I shake my head frantically, "No! May, I swear. If you don't believe me, you can see tomorrow, okay? And it's okay that Morgan stays tonight, right? We can have a sleepover!"

There is pity in her eyes. "Sure, Pete. Of course. You wanna go play with her while I make some dinner for us?"

I nod, then head back to the living room. "I heard you wanted me to help you build your Lego castle, huh? What kind of castle are we building?" She leaps up and hugs me, half climbing on my shoulder when I sit cross-legged on the ground. "Woah! Hey, careful there! You don't want me to accidentally drop you, do you? Or do this?" I stand up, Keeping her balanced on my shoulder with one hand. Even if I wasn't enhanced, I probably wouldn't have a problem picking her up. She's light.

I wrap her legs around my neck, so her legs are on my left shoulder, with her shoulders on my right, and her torso curled around my head, then start to spin in circles, slowly at first, picking up a little more speed when she wraps her arms around mine, shrieking with joy. It's loud right next to my ear, especially with my enhanced hearing, but it's worth it to hear her laughing.

I only spin a few more times before I put her down, laughing but watching carefully as she staggers a bit, before falling to her hands and knees. She's still giggling when she looks up, her bright eyes meeting my own.

"Hey, why are you sitting on the ground? We gotta build the castle! Come on!" I bounce away from her before laying on the ground where she had been sitting, then start picking up and examining some of the pieces. "I'm gonna finish this without you if you don't hurry up!"

"Petey! This is your fault! I'm toooo dizzyyyyy!" She giggles again. "You made me dizzy Petey! I can't walk anymore. You're gonna hafta carry me. Pick me up, pick me up!"

I roll back over to her. Instead of picking her up, though, I simply grab one of her ankles and slowly pull her towards me. 'Come on Morgie, you don't get to be lazy, we gotta build your castle. Are you going to help me, or do I need to do it all by myself?"

"Ugh, fiiiinne. Why do I gotta do everything? But can we get a juice pop after dinner then?"

I wink at her. "You'll need to ask Aunt May, but she can't say no to TWO pairs of puppy eyes, can she? I bet she'll say yes."

We finish the castle, and soon, Morgan has me using the princess figurine to play being stuck in the castle, while she uses her Iron Man and Spider-Man lego figures to rescue her, one in each of her tiny fists. On one hand, seeing her play with them makes me kinda sad, remembering what we lost all those months ago, but on the other, I'm excited and hoping that Mr. Stark, Michael, Captain America, and the Black Widow will be able to stay on our Earth.

I get lost in thought quickly. There isn't really much effort required to be a damsel in distress. A few 'Help me!'s and 'Save me!'s go a long way towards really selling my role. When I hear Morgan's quiet "Help!" I jerk out of my thoughts quickly, directing my attention towards her.

Wait a second. "Hey! That tiny little bridge would NOT keep Spider-Man trapped! And HOLD ON, if Spider-Man can't lift it, there is NO WAY that Iron Man could pick it up without my help!" I poke her side gently, not sure if I should actually be offended or not. She laughs again, and I can't help but smile. The little brat. Oh well, at least I love her.

I can hear May coming up behind us. "Hey guys, I made mac n cheese, are you guys ready to eat?"

Me and Morgan make eye contact, an unspoken agreement between the two of us, before we stand and race to the kitchen, her on the floor, with me crawling on the ceiling above her, leaving May shaking our head at our antics.

Dinner goes smoothly, and as I anticipated, it doesn't take much to convince May that we should have the sweet treat after we finish.

When I offer to clean up dinner, Aunt May nods, then goes to bathe Morgan. It doesn't take long, and soon enough, the kitchen is clean, Morgan is bathed, and I have showered. The three of us watch part of an episode of some kid's show before Morgan falls asleep.

She isn't normally a light sleeper, but for some reason, she keeps shifting in her sleep. Standing, I hug May, then carefully scoop Morgan up, holding her protectively. Immediately, she is calmer, snuggling into my chest. Aunt May walks ahead of me, opening my door and pulling down the blankets on my bed before hugging me softly and kissing my cheek.

I blush, but don't want to wake my psuedo sister, so I don't say anything, opting to put lay her down on my bed, then turning to hug my aunt for real. We whisper a quiet good night to each other, and she leaves, closing the door softly behind her.

I look down at my bed. I had set her down close to the wall, and already she is rolling in her sleep, trying to find my warmth. I lay down next to her, easily seeing her, even in the dark room.

As soon as I pull the blankets up around us, she manages to tuck herself into my side, curling up under my arm. I allow her to get comfortable, waiting for her to settle before I, too, drift off to sleep.

A/N: Should I bring Harley into the story? Also, please leave a review, I love reading them!
