The next day at school, Steve and Aurora were acting weird. They were constantly whispering to each other and passing notes. Tony did his best to ignore it. Then they did something he just couldn't ignore. He caught them both going into a supply closet together, during the short amount of time between classes.

"OK, what the fuck?" he said to Bruce. "Steve said they weren't dating."

"Maybe he lied." Bruce said. "We don't really know him all that well, do we?"

"I'm getting to the bottom of this." Tony decided aloud. He marched over to the closet and let himself in. To his surprise Steve was in there by himself. He stared at Tony fearfully.

"What the hell are you doing Rodgers?" Tony asked. Steve squirmed.

"Uh." was all he said. Tony looked at him skeptically. Steve continued to squirm. Something darted past Tony's feet. He spun around, expecting a mouse. Instead there was some strange humanoid creature standing there. It had grey-translucent skin, had four fingers on its hands, three toes on each foot, and big orange eyes. The pupils in its eyes were horizontally slit. It was wearing some black skintight outfit. The whole thing was about six inches tall. Tony gaped at it, before deciding it was some kind of toy. Then it moved again, looking at Steve.

"I think we're busted." it said. Tony gaped some more. Moving in closer for a better look, he saw that it had a somewhat feminine figure. It blinked sideways, its eyelids were on the left and right sides of its eyes instead of the top and bottom. It pointed at Tony.

"Stay where you are, or else." it threatened. Tony stopped gaping at it, and instead snickered.

"What are you gonna do, small fry?" he asked.

"Blast you with phasers on full power." it deadpanned. Tony laughed. Then he stopped as a thought occurred to him.

"Wait, what? Are you an alien?" he asked. It looked at Steve, then back at Tony. Steve looked at it, then back at Tony.

"You don't know what it is?" Steve demanded. Tony shook his head, perplexed. Steve sighed in relief.

"I guess we can trust you then." the creature said, thoughtfully. "Can you keep a secret?"

"Depends on who I'm keeping it from." Tony said, truthfully.

"Well, at least you're honest." Steve said. The creature narrowed its eyes.

"What do you know about Yeerks?" it asked.

"Yeerks?" Tony echoed. "Is that even a word?"

"It's a word. Pronoun. Name of a species." Steve said cryptically.

"Never heard of them." Tony said. "You wanna tell me why there's an alien in the school closet?"

The creature and Steve exchanged a glance.

"He doesn't seem to be lying." Steve said. The creature nodded. Then something incredible happened. The creature glowed light blue from the inside out, then began to change shape. After about thirty seconds it was no longer a miniscule alien. Instead Aurora was standing in front of him.

"You ever see that old movie: Invasion of the Body Snatchers?" she asked.

"Wait, what?" Tony demanded.
