During some stupid argument between the two of you, you accidentally made Scaramouche fall down the stairs.

And now here he is, in the hospital with his head wrapped in bandages and his leg in a cast and other injuries. By all accounts, you took on the responsibility of taking care of him even though he constantly whined about it.

"I should have had a prettier nurse instead of someone who could give me poison at any time."

He's sarcastic, restrain yourself from punching him.
