Jason had gotten beat up pretty badly on a mission and your boyfriend let him crash until he was better.
The two were friends, for the most part at least. Your boyfriend mostly just offered because he owed Jason several favors.
Jason noticed how shitty your boyfriend was towards you.
He couldn’t help but think how much better he could treat you, not that he’d act on it because you were in a relationship…right?
Your boyfriend told Jason how you were a nurse so you could patch him up—without checking with you prior if you were even okay with it.
You were a little annoyed but still helped him out, having several questions about how he even managed to get wounds like the ones he had on his body.
“Don’t ask,” Jason muttered as if he could read your mind, grunting at every touch of your fingers on a fresh wound.
