Pffft WELL she would only be confronting him about it in the first place because she's still very much a lesbian in this AU and would probably be kind of excited to meet someone else who's queer. Though teasing him that she might tell at first would probably happen because she's terrible.

MURDER IS BAD, YES. Though hey, there are incidents of people surviving after being hit by lightning, so we could always go that route and then he'd just have to deal with her being burned. That'd probably be easier to fix than the whole dead thing.
