The gang finally gets the epic faceoff with the Dominators. It’s silly, but pretty great. They beat back the alien invaders (shocking, right?), and everyone holds hands and hugs (literally) in the end.
Coulson, Fitz and Robbie are out of phase with reality and have to fight their way back. Mack gets possessed by the Ghost Rider and it is awesome. The LMD Aida saves the day, but now she may know too much.
Barry gets all the heroes together to take on aliens. Most of them get brainwashed, but Barry tricks Supergirl into stopping it. (Future) Barry’s message from Legends of Tomorrow is to not trust (Young) Barry. Uh-oh.
On this installment of "Tales from the Walkers," the show feels even more like anthology as the narrative focuses almost entirely on what's happened to Tara and Heath as they've been foraging in the wilds for supplies.
Cyborg Superman is (the real!) Hank Henshaw. Jeremiah Danvers is alive, and helps Kara and Mon-El escape from Cadmus. Martian Manhunter is turning into a White Martian after his blood transfusion. Oh, and Alex is still working through her feelings for Maggie.
The gang picks up an anomaly in 1874, which leads them right back to their old pal Jonah Hex. An opportunistic businessman is mining dwarf star, and takes over half the country in the future. The team goes full-on wild, wild west to stop him.
Vigilante starts dropping bodies ala Season 1 era Oliver Queen. The parallels are not all that subtle. Oliver meets Kovar in the flashback story. Quentin finally tries to face his demons. Oh, and Diggle is getting tired of life as a fugitive.
