It definitely should happen! It's canon that he's a fan, after all. *grin*

I've never seen BSG, though this is something I plan to change soon. As such, I can't say for sure what Sheldon thinks of any individual character. I'm trying to get hold of the show right now, so hopefully I'll fix that before long.

And he has now been told that some people are fictional and shouldn't be told about this, so hopefully we'll be on safe ground when they meet. *grin*
