It's reasonable to assume that anyone who would be genuinely attracted to someone like Chris is probably a pretty loopy motherfucker themselves. Or who knows, maybe he's somewhat more tolerable to be around now that he's permazooted on anti psych meds.
Still pretty fucking weird that nobody knows anything at all about Flutter. My personal theory is that she's some turbo autist who never maintained an online presence anywhere and happened to meet Chris at a group home or an event or something, only vaguely aware that he was big on the internet in some capacity. I don't know how likely that is, but baseless speculation is kind of all we have to go off right now.
