At the very end of the series finale, there are a bunch of shots of the cast at Noel's wedding. I'm sure everyone who watched this episode noticed that Alana was at the wedding...but she is supposed to be dead! The producers probably just wanted to include the entire cast since it was the last episode, but I thought it was really weird to see her there. If they wanted to avoid this, they could have just not killed her off in the first place....it never really made much sense anyway.
