It’s real, “Supergirl” and “Arrow” have crossed paths and nothing could be more exciting. “Arrow” star Stephen Amell shared the photo of himself suited up as the Green Arrow, side by side with “Supergirl’s” Melissa Benoist in all her red-caped glory.

Throwing “Supergirl” into the mix makes for what is already a very interesting 100th episode of “Arrow.” Amell previously shared photos of Deathstroke (Manu Bennett) and a mystery character on set for filming. While it’s entirely possible Benoist was the mystery person Amell was keeping a secret, chances are there are a number of surprises in store for episode 100.


“Arrow” episode 100 — which is part of the annual crossover — is in production now. The Season 5 premiere of “Arrow” is Wednesday, Oct. 5 at 8 p.m. ET/PT on The CW.
