User blog:Injustice god/*Possible spoilers* Harley in upcoming arrow episodes?

Hello everybody, i'd just wanted to talk about Harley making an appearance in Arrow (again), as in the trailer you see some "cut" scenes that show her seeing someone at her back and another one that show a very pale femenine black nailed hand at her door, from inside. Could it be that Harley has escaped?, or that someone has set her free?
