"Aubrey" is a voice actress in Fullmetal Alchemist. Her real name is Clarine Harp.
As Randy said on the S*P site:
However, one of the cast members has been doing anime voice dubbing for a year or so now and is going to be a guest at Kamikazecon in Houston the weekend of March 25 through 27 because of it. I was given permission to "out" them.
This is your chance to meet Aubrey, or as I know her, Clarine Harp. Go by and say hi. Despite what you think (or fear) she's pretty nice. She saves up the special treatment for her good friends like me.
How cool is that?
