He can't bring himself to describe it to her, but he'd suck it up if she asked how she died...or at least how he found her. He doesn't remember her murder (was he unconscious or did he erase that?).

At her question, he immediately pulls his hands away. Maybe she doesn't want to be pampered now...

"Yeah, I'm done... Let me turn on the shower for you..."

He straightens out and reaches over for the handles.
