Its eye for an eye.
Hell stop at nothing.
We havent seen Oliver really fall in love on the show before, Mericle says.
Were really going to explore the question: Can people change?
Were excited to explore that through the prism of Oliver.
Olivers cover has been blown, Mericle says.
The most fun part of the flashbacks is the dynamic between him and Conklin.
Were really going to be seeing those chickens come home to roost.
Olivers going to make enemies, not just with the guards, but with the prisoners as well.
Hes going to find himself without a lot of friends going forward in the flashbacks.
As for the big question of the hour whats Felicitys fate?!
Mericle teases, Shes obviously been through a hugely traumatic event.
Shes faced with a lot of challenges, not just physical, but emotional as well.
Shes got the team rallying around her.
Arrowreturns Wednesday at 8 p.m.
