Great episode, Slade's biggest moves in his game of Chess so far and he has Ollie on the ropes. In one swoop Slade turned Thea against him, took his company and exposed his secret to his former girlfriend who also works in the DA's office. On top of that, byproducts of the play by Slade have been Quentin losing his job and Roy going rogue.
Of course the latter two things are more down to Ollie's mistakes, but his realization that his bad calls as leader have been an enemy within is a big step for him in turning things around.
I thought Amell was really good in this ep and Bennett was again fantastic, I love the contrast between Island Slade and present day Slade. On the island he's brimming with intensity and barely contained rage, in the present he's cool and calculating in his actions, although we saw that fire come out when Blood questioned him.
Along with fantastic scenes from the two lead adversaries, Willa Holland, Susanna Thompson and Summer Glaiu all delivered in their pivotal scenes, and the action sequence in the warehouse with Ollie taking out the goons was another fantastic example of this shows quality stunt and fight choreography.
The final scene with the original trio sets things up nicely and played well off the scene of Felicity stepping forward to tell Ollie to go and get Thea back by any means necessary.
