This is humiliating.

Jotaro doesn't even remember why you two got into a fight, just that you both did, that you were the one who instigated it, that he threw the first punch.. and as luck has it, you were admitted into the same hospital room to get your injuries treated. You had both been scratched up, him having broken your leg and you breaking his arm. He had a black eye and his lip was cut open, an irritated expression on his face.

But what really embarrassed him was that he got his ass handed to him by YOU, some random punk he had never bothered interacting with before all this. It irks him that you managed to get the upper hand—usually he always came out of fights victorious. This one was a draw.
