Depends where you live, as I said over here in the UK they've completly messed up on Boomerang, and are calling the second half of Season 1, Season 2.
Interesing point, and maybe she does. I'll see if I can view it from that perspective. However, the description for "The Last Roundup" seems to sugest heavily that it is an Applejack episode, although, the storyline is apparently that she goes missing, so there a chance most of the episode will be focused on the others, and they're all searching for AJ, rather than us watching AJ herself. We'll have to see what they decide to do with this one...
Yeah, I think you're right on that one ("That's what I said" seemed to be directed towards the audiance for example).
