Willa Holland is all grown up — and might be a superhero!? Holland is most known for her role as Kaitlin, Marissa Cooper’s younger delinquent sister, on The O.C and also her guest appearances on Gossip Girl. She currently plays Thea Queen, sister to Oliver Queen/Arrow, on CW’s new action-adventure, ‘Arrow‘, based on the Green Arrow character by DC Comics. The pilot alluded to Willa being the superhero sidekick when Oliver called Thea by the nickname ‘Speedy’. So let the fan-fiction begin! I’m sure if the show is a hit and comes back for another season the ‘Speedy’ avenue will be taken — maybe sooner, who knows.
