OKAY, after chatting with Rust, Shaw will indeed be attempting to get herself down onto the cabin roof as quietly and covertly as possible! That said, while she knows how to jump/fall safely, she's trying to avoid suicidal recklessness here, so she'll only do it if she feels there's a solid chance she'll succeed without giving herself a serious injury! (OOCly I'd fine with it not going well, she would just have to have good reason to believe that it could.)
