Legends Of Tomorrow Midseason Finale Trailer Reveals Why The Legends Aren't In The Elseworlds Crossover

The gigantic multi-show Arrow-verse crossover is on the way, but Legends of Tomorrow won't be part of it. While the heroes of Arrow, The Flash, and Supergirl are dealing with all the "Elseworlds" craziness, the Legends will be doing their own thing. Although Legends' absence from the crossover has been known for a while, we haven't been able to say why the Legends won't be available for what seems to be an threat to the entire multiverse. Well, Legends' Season 4 midseason finale trailer reveals why:

Reality is fractured! The Legends are going to be busy fixing what they broke during the big "Elseworlds" crossover. Legends of Tomorrow is bonkers on a weekly basis, but the craziness may be at an all-time high in next week's episode, called "Legends of To-Meow-Meow." The early plot description for the episode revealed that the fiasco would start when Constantine broke the #1 rule and changed the past, despite all the grief he gave the Legends for breaking time and unleashing magical creatures on Earth.

According to the episode description, Constantine will team up with Charlie and Zari to try and fix the issue without letting the other Legends in on what was happening, and Constantine and Charlie will only make the mess bigger by trying to fix things their own way, contrary to Zari's recommendation. The description was interesting, but it left a lot of unanswered questions. For those, we can look to the December 3 episode of Legends of Tomorrow, called "Hell No, Dolly!"

Constantine and Charlie messed with time in a variety of ways in "Hell No, Dolly!" as Constantine attempted to find a way to save the man he'd loved from a horrible fate, promising to help Charlie regain her powers if she helped him. Zari's attempts to stop them failed, putting the three of them in their position in next week's episode.

Meanwhile, most of the Legends were busy trying to stop a murderous doll wreaking havoc back in 19th century New Orleans. They managed to stop the doll, burn it, and chain the remnants up to keep in the Waverider.

Unbeknownst to them, however, the thing possessing the doll wasn't dead at all, and it escaped the burnt doll to take up residence elsewhere: the ventriloquist puppet of the late Dr. Stein. It proceeded to attack Ava with a knife, and it was only thanks to Mick's intervention that the puppet Dr. Stein failed to murder Ava.

Oh, Legends of Tomorrow. Never change.

Meanwhile, back at the Time Bureau, Mona befriended a werewolf that she was meant to be taking care of, and her care ultimately led to the creature's escape, and she was seriously wounded as she tried to stop him.

Then came the really weird twist. Somehow and some way, a wave was unleashed through time and space that stopped almost everything. There was no indication of what exactly the wave had done, but Charlie got a shock when she looked over at Zari and only discovered a cat, wearing Zari's totem.

I'm not sure how all of this leads to Sara, Ava, and human Gideon going full Charlie's Angels, various Legends being turned into puppets, cat Zari working a computer screen, and all the other craziness teased in the trailer, but I'd say that it very clear we're in for a wild ride in the midseason finale. In fact, Legends may be able to cram as much craziness into one episode as "Elseworlds" will in three!

Tune in to The CW on Monday, December 10 at 9 p.m. ET to see the midseason finale of Legends of Tomorrow. For some viewing options once Legends and other fall shows go into hiatus, check out our midseason TV premiere guide.
