Yeah, seeing someone in the buff? Not part of Ritchie's plans for the day, or, well, ever. He waited for Giles to get dressed, feeling more embarrassed than he'd ever felt in his life.
Finally, when Giles came back out, he dropped his hands, but still couldn't look him in the eye. He felt kind of silly now as he said, "Er, you asked me about those, uhm, references? The, uh, cartoons? Said you were free today, so I thought we could go see 'em."
...wow, this was only going to get awkwarder as Ritchie fidgeted.
