I'm confused about that season 4 episode where Anna returns. Sydney says that she thought Anna was dead, but I don't recall any such thing. In fact I don't remember what happened to her or K-Directorate at all. After some checking around, it seems that the last recorded appearance of Anna was in "Time Will Tell", but didn't that happen before the scene in the stadium (or maybe just before)?
Either way, I've read that the last mention of either her or K-Directorate before season 4 was in "Snowman".
Did they forget about that stuff or abandon it for new stories on purpose? I love Alias but before the end of even the first season, it got too wild, too messy, with too many loose ends that they leave hanging. Did I not pay attention or is that how it really is?
