Worst Summer Vacation

Darkness. Then here.Huh. Kidnapped
The Twice-Told Tale
by arysteia
For someone he'd hero-worshipped for so long, Steve Rogers in the flesh is a pretty big disappointment. For one thing, he keeps looking at Tony as though he reminds him of someone else, and even if he never says anything, Tony's pretty sure it's his father. A lifetime of not measuring up to Howard
Slide To Answer
by relenafanel
"What do I do?” Steve appealed into the phone. “I’m freaking out.”There was silence on the other end of the line. It lasted so long that Steve pulled the receiver away from his ear and frowned at it. Pay phones were old. Maybe this one wasn’t working despite the obvious dial tone when he picked u

Repeat After Me

That was oddly specific. Glancing down
Constant Internal [Spider] Screaming: Semi-Connected Scenes from a Graduating Senior’s Life
by isaDanCurtisproduction
When Peter's Teacher announces that his Graduating Class's Senior Trip is going to be to Stark Industries, the place where Peter has an internship, and where he spends so much of his free time, he is... less than enthused.

Hot Chocolate

Do you want some hot chocolate
I Think I Missed a Step ('Cause I'm Fallin' For You)
by mokuyoubi
There’s a weird familiarity about the kid's tone and posture, and it’s true that Wade is pretty far from home today but he’s also certain he’d remember that baby-face if he’d seen it before.
