I'm not really confused..I mean I guess a little but that's just part of why the show has always been so good to me..trying to figure it all out

. But they are dropping HUGE answers to questions...we now know for certain that the ATL isn't just filler ..it serves a purpose..which Desmond is apparently the key to. The bomb must have been a "reboot"...it altered their lives to how it would have been if the crash hadn't happened..but it's not an "alternate reality/universe" kind of thing...they DID go to the island...those things did happen to them and they're starting to remember.
I loved the scene with Des/Charlie in the car...that was an awesome way to jolt him into remembering.
And Eloise knows...she seemed to know a lot when she was talking to Des...and of course she wants him to let it go..b/c in the ATL Daniel is alive.
