yes! vash was one of the first humans he met and he completely ~ruined~ humans for him because no one is as entertaining. BUT apparently it was right around the time that vash ghosted on her? so when they actually get to meet he'd be like "oh you're the one whose heart he broke while simultaneously hurting himself, nice to meet you". or something. I imagine he at least caught the tension coming off him and asked about it because what is privacy?
