Quentin collapses as a result of his injury. Production Development On February 11, 2013, The CW renewed Arrow for a second season for the 2013 - 14 season. A backdoor pilot for The Flash was originally going to be the twentieth episode, but due to the positive reception of Grant Gustin 's appearance in the eighth and ninth episode, executives at The CW scrapped it in favor a traditional pilot so that it gives the developers more time to flesh out the character in addition to receiving an increase in the budget. Casting Emily Bett Rickards, Colton Haynes and Manu Bennet were all promoted to series regulars. Jacqueline MacInnes Wood, who originally played Sara Lance in the pilot, did not return and was replaced by Caity Lotz. Costume design In the second half of season two, Oliver replaces his `` paint '' mask with a domino mask, similar to one worn by the character in the comics. The change is addressed on - screen, with Kreisberg saying, `` He does n't just put on a mask. It 's actually a big plot point in an episode, and there really is a story behind, not only the need for the mask but also who provides him with it. '' On adding the mask now, Kreisberg stated that, `` Conceptually, it was something we wanted to do because Oliver himself is evolving as the Arrow -- from vigilante to hero, sort of from Arrow to Green Arrow -- and we wanted to see that progression in his costume as well. As Oliver is embracing being a hero, being a hero means stepping out of the dark and being more of a symbol, so he has to take steps to conceal his identity more. '' He added that it will `` allow the Arrow to interact with people who do n't know his identity in a much more organic way than having him constantly keep his head down. '' Costume designer Maya Mani put together roughly 50 mask options for the producers. Kreisberg said, `` What 's so wonderful about the design that Maya came up with is that it really is very simple, and it feels as if it 's been part of his costume since the beginning... once we finally had this mask and put it on Stephen ( Amell ), even Stephen was like, ' This is the right one. ' '' In the episode `` Three Ghosts '', Oliver receives the mask from Barry Allen, who is able to create a mask that will help conceal his identity, while still being functional and allowing Oliver to see clearly.

She said, `` Arrow ( has ) officially established itself as one of the most satisfying shows on television. The most satisfying thing of all is that it did so by respecting its characters...
