Caity Lotz has confirmed that Sara's personality would be different in the new show, no doubt a result of the Lazarus pit. My speculation/guess is that in the season 4 premiere Nyssa and the new Malcolm-Ra's revive Sara, and since she was dead for so long, she'll be psychotic and hell bent on revenge (maybe on Thea?). But after a nice Black and White Canary showdown, Sara is reminded of who she was through Laurel and slowly becomes more sane. At the end of her de-psychofication she'll be like she was before the gambit incident, but with memories of everything she went through, just not as dark as she was in season 2, because let's face it, she was way worse than Oliver was in s1. Like I was saying, in the LoT trailer when she asked Ray about him not-dying-but-shrinking she reminded me of the flashback in Arrow when she came in from college to see her family. Sara after the gambit could never see herself as a hero, but pre-gambit Sara could. Let me hear your thoughts!
