The episode is titled "This is Your Sword" and, like the penultimate episodes of Seasons One and Two, it's named after a Bruce Springsteen song.
This time, though, they didn't use something off The Boss' 1978 album Darkness on the Edge of Town, as they have in each of the previous two years. This time, it was a track off of Springsteen's 2014 record High Hopes that provided the episode title.
This title, along with a leaked set photo from The Flash, may raise some very interesting questions about the episode's content, but we'll leave that speculation to the Internet for now.
Arrow airs on Wednesdays at 8 p.m. ET/PT on The CW.
