Omg definitely Nathan Fillion!

I remember seeing a picture of him visting the set (aha! here it is:link) and thought wouldn't it be great if he guest starred! Nathan would be just epicness!

Nathan Fillion is Richard Castle right?

My pick wins first!

I hear this question and I immediately think Nathan Fillion. I then remember the rest of the cast and get all choice-makey. I fraking love Alan Tudyk. But I think if someone were to be working side-by-side with Adam Baldwin, I would have to choose either Nathan Fillion or Jewel Staite. Only because they'd be my personal favourite characters to work with Baldwin. Plus I haven't seen much of Jewel Staite in much of anything else, so that would be nice. Come to think of it, Gina Torres could TOTALLY get all but-whooping with the whole secret agent factor. Thinking again, Summer Glau AND Morena Baccarin could both also get ass-whoopy. And Sean Maher could be all dorky, Ron Glass all wise-like. Damn this thinking process. I'm going to stick with my answer of "EVERYONE".

/end creepy essay.

Summer Glau has already been on so I pick Gina. She makes an awesome villain!
