We've just started on the second season - watched the first two eps of that last night. On the credits at the end of the first ep ("When She Was Bad") was a listing for "Tara". Huh? There was no Tara in that episode - I'm sure I'd have recognised her from all of glitterboy1's icons, if nothing else! - and I had somehow got the idea that Tara doesn't appear until the 5th season, although admittedly I don't know where I got that from. The second ep ("Some Assembly Required") didn't have that credit.
I don't want to go look at episode and character guides for fear of spoiling myself in a major way, so can anyone enlighten me??
