Isn't her deal like Wentworth Miller's? As in, appearing multiple times, but not as a main cast member?

Well, regarding Arrow, I guess it will go this way: first half of the season we'll see her in flashbacks, then the reveal happens midseason, and the second half tells us how she faked her death.

Regarding her appearances on other shows? No clue. On Flash she may be in Flashpoint, then Siren may be part of some meta-uprising in the usual episodes. On LOT they can just travel back to the time period when she was alive.
