The CW has released two new clips for "Irreconcilable Differences", tonight's midseason finale of Arrow's sixth season.
The first video shows a scene from tonight's episode, which takes place at Oliver Queen (Stephen Amell) and Felicity Smoak's (Emily Bett Rickards) wedding reception.
They might be celebrating their spontaneous (arguably to a fault) nuptials, but Quentin Lance (Paul Blackthorne) soon comes with bad news. Someone in Team Arrow is serving as a mole for the FBI, and it's up to Oliver to find out who.
The second video shows a version of that same scene, plus a bonus bit of Oliver telling John Diggle (David Ramsey) about the FBI mole. As he explains, either Curtis Holt/Mr. Terrific (Echo Kellum), Rene Ramirez/Wild Dog (Rick Gonzalez), or Dinah Drake/Black Canary (Juliana Harkavy) gave Oliver up to the FBI, and they need to find out who it is before the rest of the team is dragged into the mud.
"[The episode] picks up, pretty much directly after the events of our annual crossover." executive producer Marc Guggenheim explains in the video. "There were some pretty big developments for our Arrow characters, and you will see the ramifications of those elements."
"It features some pretty big surprises, you know. It's our midseason finale, so expect some game-changers."
Arrow airs Thursdays at 9/8c on The CW.
