Later when Jaskier is in the tub trying to get rid of the fucking smell, he does panic a little. He reacted on a whim, eager to stab Joel where it hurts.

But he also remembers Midge's amazing smile and the very cute squeak, and thinks it's worth it to make her so happy. She deserves to have an emotional shield at that fucking wedding if her whole family is going to act like Joel did today. He remembers his childood during events like that, and he wants to save her from the same fate.

The way it makes his heart beat is dangerous. And like the dumbass he is, he ignores it.

Jaskier is about to fall asleep in the tub when he gets Midge's text. He smiles.

Of course. I wouldn't joke about something like that.
