At the sound of someone entering the room, Cisco looks up and the confusion and surprise at the fact that a) she's a she, and b) she's covered in soda and wielding a piece of friggen robot like a weapon absolutely registers on his face. He sits up and that's when he notices that she's actually started undressing, probably because she hadn't realized he'd be laying there — as evidenced by the way she stops short and stutters out something that sounds a little too much like the sort of thing he'd say in her shoes for him not to decide he already likes her.

His hands go up defensively and he turns his head. "I didn't see anything," he replies quickly by reflex. "...that's a lie, sorry, I totally did, but I wasn't looking, if that makes you feel better," he adds in defensive apology.

It isn't until she introduces herself and he actually gets a good look at her face that Cisco looks back at her with recognition. "Stop it," he says playfully, tilting his head a little as he grins before sitting up straighter. "No you're not. Shut up, are you?" Buffy. Like...the vampire slayer? Like, the TV show he vaguely remembers watching in the "glitches" he's still not entirely sure aren't memories?
