The only thing anyone in the ep description got right was Helena coming to town. Roy, going by Oliver, breaks up with Thea (steady, berserker-stopper and boss!) and she's consequently picked-up by Slade! Oliver, instead of owning all the shit he's let Thea deal with, lets her marinate in the feeling of betrayal/lies of omission everyone but (supposedly) Oliver has handed her. Laurel, while her intentions were heroic in wanting to save the hostages, she ended up not helping things in the end. Then blackmailing the DA for her job back? These folks didn't mind if you were killed by Helena, a psycho in their eyes. (To be fair, Helena's give a damn broke, but yeah, she's a murderer.)
Not dissimilar to the "Does Quentin know?", is my "How could Laurel not know?!" Surely she's seen her sister a time or two since Sara revealed herself to the family. Plus, all the growing up years? *sigh*
Felicity and Digg's "kick her ass" agreement was great. Not only was it funny, but it served better than the episode "Blind Spots" where Oliver has his. Then again, just about everything Felicity and Digg is gold, imo.
I just hope, for Thea's sake, there are some actual truth bombs laid on her; she is so going to tear Oliver and Roy new ones if she gets a chance.
