I play 6 degrees of X-Files as well as BTVS/AtS. It's so fun to do, isn't it?! That's neat that you recognized Rowland from X-Files, he was just a very scary/creepy guy for me when he was on AtS. He's so very good on VM, and I'm figuring we'll see him again.

And Fredric Lehne - he played 'young Arthur Dales' the FBI agent who originally discovered and worked on the X-Files in the 50s.
That's such a neat connection!! So many Jossverse/X-Files connections on Bones!

And Smallville? Well, it was just so James-less... I know! It made me very sad.
