After looking at the photographic evidence, I think Hot Dog might be on to something. Maybe she's a sister. Maybe she's a long lost cousin. Maybe Jaime Edmondson just wanted to back into the cheerleading world without anyone knowing. Amy's MDC profile page doesn't mention anything, but I know a conspiracy when I see one.
I'm going to need some definitive proof before I believe this isn't actually Jaime Edmondson cheering under a pseudonym!
