"Do you think I'd explode if I drank this?" You asked and swished around the insides of the beaker you were holding. Peter looked up at you through his lab goggled and chuckled.

"I don't know. You should try it."

"You say that now but you'd be so sad if I exploded." You insisted. "You'd have no one to watch Over the Hedge with."

"Wait, can we watch Over the Hedge tonight?" He pleaded. "I forgot about that movie. I love it so much."

"I know you do. Which is why you're gonna be sad and alone watching it tonight and thinking wow, I wish I didn't let my best friend explode." You shrugged and put the beaker down.

"Um, excuse you. I would never be best friends with a girl. You have cooties and go to Jupiter to get more stupider."

"Oh, but that's where you're wrong." You chortled. "Because I actually went to college to get more knowledge. It's boys who went to Jupiter to get more stupider."

"But if I, as a boy, successfully figured out how to travel to Jupiter, wouldn't that make me the smarter one? Since I cracked interplanetary travel?"

"I think you should drink this." You said after a beat of silence and held the beaker up. Peter laughed and you did too. He snuck another glance at you as you combined the contents of two flasks and made a tiny explosion. You often accompanied him in the lab when he was at the Avengers tower despite not being much of a scientist yourself. You just liked to help and watch as he did his thing.

"Thanks for helping me, by the way." Peter said. "I'm sure you have a million other things you'd rather be doing than helping me develop new kinds of web fluid."

"I don't mind." You shrugged. "If you throw out the words "tornado web", of course I'm gonna want to help you make that possible. Plus, I like spending time in the lab with you."

"You do? Because so do I." He said as a blush covered his face. You looked up from what you were working on and gave him a smile. Peter sucked in a sharp breath and cleared his throat.

"Um, so, I'm just gonna throw this out there and you can tell me how you feel." Peter began. "I was wondering if maybe sometime you'd want to-"

"Where is she?" Peter was cut off by an unfamiliar voice booming through the lab. You immediately looked up and pulled your goggles down.

"Harley?" You asked, sending a twinge of jealousy down to Peter's stomach.

"Who?" He asked you. His question was answered by a tall, sandy blonde guy walking into the lab. He wore an oversized corduroy jacket with patches on the elbows that made him look the kind of effortlessly cool Peter could only dream of looking.

"Harley!" You exclaimed and put your beaker down to run to him. Peter watched with furrowed eyebrows as you threw your arms around Harley's neck and hugged him tightly. Harley wrapped both arms around you and lifted you off the ground as he spun around.
