You are sick and so is Peter. Bruce is examing you and the other Avengers are staring at you both, the most of them can't get sick or almost never get sick

Bruce: Geez, you have a fever of 104... Peter only has 101.

Peter: I don't feel so good... I am so sick.

Tony: yeah kid, you will be staying here today.

Yelena: Oh shit up, she has even higher fever!

Natasha: Yelena, it's "Shut up", not "Shit up".

Yelena: Ugh, whatever.
