Is Arrow new tonight, November 30?

Arrow won’t air at its regularly-scheduled timeslot and date. Why is this the case?

Arrow remains a mainstay of the CW’s aptly-dubbed Arrowverse. In its sixth season, Oliver Queen and Team Arrow continue to protect Star City from dangers that arise, including Cayden James, Black Siren and anyone else that heads their way.

Starting with the season 6 premiere, Arrow aired on Thursdays at 9:00 p.m. ET. It’s unusual because this show was always on Wednesdays at 8:00 p.m. ET. Instead, Riverdale took this timeslot, while the CW shifted around its programming.

So, entering Thursday, Nov. 30, you’re probably expecting season 6, episode 9 of Arrow. However, that won’t be the case, as this week’s episode already aired on Monday, Nov. 27. It was moved up for the four-part crossover, “Crisis on Earth-X.” This brought together Ollie and company, along with the casts of The Flash, DC’s Legends of Tomorrow and Supergirl.

By moving Arrow to Monday night, it condensed the crossover into two nights. Otherwise, it would have been four shows over four nights, with two of them (The Flash, DC’s Legends of Tomorrow) airing on Tuesday.

A new episode won’t air until Thursday, Dec. 7, titled “Irreconcilable Differences.” In the CW-provided promo, a traitor was teased, with it potentially being someone on Oliver’s team. Will it have anything to do with Agent Watson’s investigation into the Mayor of Star City?

Expect fallout from Oliver and Felicity’s marriage, too. That’s no typo, as they didn’t get engaged but married at the end of “Crisis on Earth-X,” using John Diggle as the Justice of the Peace to marry them. It happened simultaneously, with Barry Allen and Iris West finally tying the knot, thanks to the Earth-X Nazis thwarting their wedding in Part 1 of “Crisis on Earth-X.”

Viewers must wait seven days to get their final Arrow fix of 2017. Following “Irreconcilable Differences,” the show will go on winter break and return in January 2018.
