As I just added in Adul's thread, after watching tonight's ep, I'm more convinced they are going to find a way to make Mulder the baby's dad.
Gillian Anderson has already signed a contract for another season, and the guy playing Doggett says he'll sign on too if his character works out. From what I understood, Duchovny will appear in 11 of the 22 episodes this season, and will only be back full-time for 8 of those 11.
It would be nice to see some actual closure on the CSM thing - is he dead? I know Krycek and Covarrubias shoved him down the steps and he looked dead, but he has an annoying way of turning up again.
I liked Doggett - I think his character has enough play to either be a bad guy, or if the chemistry works with Scully, to be a long-term good guy.
Big Bwana - I agree that "to be continued" are the most dreaded words at the end of an ep. Especially since Carter seems to like drawing his ep arcs out for more than just two shows. I can tell it's going to be a frustrating first half of the season.
