[Not exactly the reaction she was expecting, when he's left just staring at her for a few seconds. Did she say something weird? It's deeply uncomfortable for her to be on the receiving end of that look. She's about ready to ask what his problem is when he lowers his face into his hand and... That explanation makes her pause, too.]

...Are you serious? How do you just forget that you have a spell? Do you practice magic at all? [It's a very serious study, how do you get away with just forgetting things?? But the fact that he's staring because of his own dumb fault and nothing to do with her is relieving. She doesn't side-eye him for too long.]

I guess you don't need me to make you potatoes, then. Unless you forgot how to cast it, too.
