Happy Thanksgiving! Because of the holiday, there will be no new Legends of Tomorrow episode tonight.

After the last episode, “Outlaw Country,” reunited the Legends with Jonah Hex in the Old West, Legends of Tomorrow is taking a week off for Thanksgiving. It will return next week with the final installment of the four-part Heroes v. Aliens crossover between Supergirl, The Flash, Arrow and Legends of Tomorrow.

The CW will air reruns of Whose Line Is It Anyway? from 8:00 p.m. to 10:00 p.m. ET on Thursday, November 24. Legends of Tomorrow will have no new episodes this week.

Watch a trailer for the four-series crossover:

The CW has also released a neat clip of “found footage” of the Dominators:

The synopsis for the Legends of Tomorrow portion of the crossover reads:

ALL FOR ONE AND ONE FOR ALL IN THIS CROSSOVER OF SUPERHEROS — After learning the Dominators’ plan for the world, the Legends must work together with The Flash (guest star Grant Gustin), Supergirl (guest star Melissa Benoist) and Green Arrow (guest star Stephen Amell) to kill them once and for all. Meanwhile, Stein (Victor Garber) figures out, with the help of others, how the team can terminate the Dominators, but is distracted by the aberration he realizes he created in 1987. Brandon Routh, Franz Drameh, Dominic Purcell, Maisie Richardson-Sellers, Nick Zano and Caity Lotz also star. Gregory Smith directed the episode written by Phil Klemmer & Marc Guggenheim (#207).

While the bit about the Legends teaming up with the other heroes is vague, we do have some hints about the second half of the synopsis. We saw in “Outlaw Country” that Stein was being assaulted with visions of a mystery woman who Stein felt like he loved. He and Jax deduced that interacting with his younger self in 1987 created some kind of aberration, and now it seems like it may have affected his marriage to Clarissa.

Legends of Tomorrow 2×07 “Invasion!” airs Thursday, December 1 at 8:00 p.m. ET on The CW.
