The cast of "Arrow" is keeping Twitter awake and guessing with teaser pics from the CW superhero show's set. In addition to an image posted by Wild Dog actor Rick Gonzalez teasing the upcoming crossover event, "Arrow" lead Stephen Amell has posted a bloody selfie indicating that he shot quite a violent scene over the weekend.

Hope everyone is enjoying their weekend as much as I am. pic.twitter.com/Mw7znf7GFm— Stephen Amell (@StephenAmell) October 22, 2016

And before you go and wonder if these injuries were caused by the alien Dominators, the central bad guys in the upcoming CW crossover event, take a closer look. Amell is sporting long locks and facial hair, indicating that this beating he takes will occur during one of "Arrow's" trademark flashback sequences.

Starring Stephen Amell as the Emerald Archer, "Arrow" airs Wednesdays at 8 pm ET/PT on The CW. The series also stars Emily Bett Rickards, David Ramsey, John Barrowman, Willa Holland and more.
