Buffy wasn't even aware Wesley existed in this world just yet, but hearing the news from him would probably have sucked just about as much as figuring it out on her own by surfing the internet. Which was never a thing she thought she'd be interested. Especially not after Willow's creepy internet boyfriend that was actually a robot incident. She'd been turned off of things that were tech related since then, and even now she was wary. But it was more than obvious times were changing, so maybe not all computers had robots using them. She hoped anyway.
"Superman.." She raised a blond eyebrow at Cordelia. Xander would be in comic geek heaven to meet Superman. Honestly Buffy wasn't sure whether to laugh or continue staring skeptically-so she chose the later and let her Frappichino melt a little more. "..We're fictional? So that means what? Everyone knows about everything I've ever done?" A sense of sudden panic, but she was in a public place. She wouldn't have a melt down in a public place.
