"Kid," Tony whispers from his place in the line of groomsmen, kicking his heel softly. "You okay?"
"Y-yeah," he whispers, not wanting to take the attention on the altar away from May.
May's always made everything about Peter. Always. And that fact only intensified after his type one diabetes diagnosis three months ago.
But today? Today is about May. About Happy. About the two of them choosing each other and being happy together, and Peter has done everything he can think of to keep his diabetes and his tendency to be an absolute klutz from interfering with that fact.
"I now pronounce you husband and wife. You may kiss the bride," the officiant announces, the small crowd cheering as May and Happy kiss. Peter smiles and claps, feels his body sway a bit and blinks his eyes as he steadies himself.

Dexcom says he's fine.
He's fine.

"You probably guessed it wasn't Avengers related, so I'll get right to it. There's an SI Gala going on this Wednesday, and for the last month and a half I've been dreading it. The usual boring business shenanigans. Then, a brilliant idea pops into my head, pretty usual occurrence for me I know-"
"Is there a point to this?"
"But," Tony continues as if he wasn't interrupted,"who am I to decline my own genius. So," he turns lazily on his heel to suddenly face the doctor with a confident smile, "be my date."
Or: Tony takes Stephen out on a surprisingly thoughtful date to convince him to come to a Stark Industries Gala. Stephen thinks it'll be easy to go through the motions, but when Tony turns out to be genuinely considerate, he's not so sure. However, like everything else in Stephen's unpredictable life, things go off the deep end when it turns out Tony hasn't been entirely truthful about his motives.
