I was watching "Buffy vs. Dracula" recently, and the interaction
between Giles and Riley caught my attention. I've also recently
heard a few versions of Sweet Transvestite performed by ASH. These
things combined to give me a strange fic idea. I decided to
post it as a challenge.

The Challenge:
Riley secretly goes to RHPS and is a cast member.
Giles finds out about it, and Riley doesn't want anyone to know.
What does Riley have to do to keep Giles silent?
How did Giles find out?
What happens if Buffy does find out?

Please keep character bashing to a minimum.
I would rather the story be about Riley and Giles finding something in common.
