This is hilarious.Sensei, I think you managed to break Claude's brain.My pulse?........soft...What do you think?Then let's do this.I would like to, but I can hardly just stick my face in your chest.Do you want to listen too?Huh. Yeah, that is definitely strange.She's got a pulse, though. That's weird, right?I can't hear it at all.Listening for her heartbeat!Just what are you up to in here, Hilda?Hey, now.
