So far, on Crisis on Earth-X, all of the heroes and legends converged on Central City to attend the wedding of Barry and Iris (Grant Gustin, Candice Patton). Of course, happiness can’t happen without hitches and glitches, so Nazis invaded the ceremony, led by evil Oliver Queen (Stephen Amell), evil Supergirl (Melissa Benoist), and the original Eobard Thawne wearing a Wells (Tom Cavanagh) face. They came from Earth-X, the 53rd earth where the Nazis won WWII. The plan? Save dying evil Supergirl by taking the heart of our Kara. Some cool battles ensued, but our heroes were left in a Nazi prison at the end of Arrow last night.

Warning! Spoilers below for the season 3 finale of The Flash!

Last season on The Flash, Savitar, aka warped Barry remnant (Grant Gustin), was finally defeated without Iris (Candice Patton) dying because HR (Tom Cavanagh) sacrificed himself instead. There was a giant fight – Killer Frost (Danielle Panabaker) ended up saving Cisco (Carlos Valdes), and Iris took out Savitar. The speed force needed a sacrifice and showed up as Barry’s mother, insisting he needed to go love there or worlds would be destroyed. Julian (Tom Felton) made a cure but Caitlin didn’t take it, although she was on a path to redemption.

Warning! Spoilers below for the season 3 finale of The Flash!

Last week’s Flash was full of tears, as Barry (Grant Gustin), desperate to save Iris (Candice Patton) as the clock wound down, went back in time to get Captain Cold (Wentworth Miller) to help him steal an energy source from A.R.G.U.S. This energy was needed to fuel the “speedforce bazooka” that Tracy Brand (Anne Dudek) built, inspired by her muse and crush HR (Tom Cavanagh). After a harrowing reenactment of Jaws, they retrieved it and Barry and Snart said goodbye in a bittersweet moment for Captain Cold fans. The team went to Infantino Street to stop Savitar from killing Iris, but it didn’t work. Savitar ran Iris through and Barry held her body in his arms. Vibe (Carlos Valdes) and Killer Frost (Danielle Panabaker) faced off.

Last night on Supergirl, a musical was briefly mentioned as a suggestion for a movie from Mon-El to Kara (Chris Woods, Melissa Benoist). Then… at the end of the episode, an alien was brought in who spoke to Kara, “I’ve been looking for you.” He breaks out of his cuffs and whammies her with his eyes. She passes out and opens her eyes to a dream state where she is all dolled up and pushed onstage to sing.

Last week on The Flash, the team sans Wally, Jesse, Iris, and Joe (Keiynan Lonsdale, Violett Beane, Candice Patton, Jesse L. Martin) rolled to Earth-2 to save Harry from Grodd (David Sobolov). It’s a trap! Grodd told Barry (Grant Gustin) he had to kill the Gorilla City leader, Solovar (Keith David), because of a plan to attack Earth-1. Barry fought and defeated (but didn’t kill) Solovar, and then Grodd revealed the real reason… Solovar was the one preventing Grodd from attacking Earth-1’s Central City. They all got locked up again, but Barry played dead via “frost.” When Grodd threw his body onto the trash heap, Barry warmed back up, and they all escaped back to Earth-1. Wally and Jesse grew closer, while Caitlin warned Julian (Danielle Panabaker, Tom Felton) away (he didn’t listen).
