We all knew the flashbacks are all messed up and this episode proved that in a whole new level.
Andy worked for the same person that Oliver was caught by. The same map he has and now the flashback has integrated Andy as part of the story.
In the present day, two agents got killed and we end up seeing that Shadow guys former military attack Argus and man they killed one of the most powerful people without thinking through.
At the same time Felicity had her moments of hallucination.
Not much in this episode as we just got a lot of happy endings style things. Kind of boring.
