I'm a huge fan of Sara, so I'm very disappointed that she doesn't seem likely to show up anytime soon. I'm reserving judgement on the new "love interest." I'll wait and see if that's what she really is in execution, and what kind of character she turns out to be.

I'm more than a little irritated with the status of this show's female population right now, to be honest. Sara appears to be gone for the foreseeable future, and Elizabeth's character, in my opinion, had been totally destroyed by the end of season 4. Maybe Diana will get some good material in S5.
