The CW realased a new trailer for the mid-season premiere of Arrow season 5 titled "Who are you" and in the end of that trailer it is revealed that the Laurel who returned isn't E1 Laurel, but in fact she is E2 Laurel or at least a Laurel with meta human powers. I know most of us already predicted this and it isn't a big deal but I kinda feel dissappionted that they revealed it on the trailer instead of doing it in the actual episode.Anyway I hope this Laurel becomes a series regular in the next season and gets a redemption arc.
