Warning! Spoilers below for all parts of The CW Crossover, including tonight’s episode of The Flash!

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.

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.

Two weeks ago on The Flash, the meta of the day was one that Alchemy aka Julian (Tom Felton) had awakened. His touch had the ability to cause matter to disintegrate, and people to decompose to ash. That meta, Clive Yorkin (Matthew Kevin Anderson), went after cops that collared him in Flashpoint. He touched Iris (Candice Patton) to hurt Joe West (Jesse L. Martin). Barry (Grant Gustin) figured that out, so Cisco (Carlos Valdes) vibed there to find the next target. Yorkin caused a train full of people to be in danger, so Barry vibed the whole train safely through, leaving Kid Flash (Keiynan Lonsdale) to vibe (for the first time) through Yorkin with a neutralizer.

Last night, Barry Allen and Cisco Ramon (Grant Gustin, Carlos Valdes) stopped by Supergirl via wormhole to recruit Kara (Melissa Benoist) for a slight problem. The episode was good, but there was definitely not enough crossover – merely the last 2 minutes. Tonight’s episode of The Flash was the payoff as the gang was all here.

Last week’s Arrow was one of my favorites, as former WWE wrestler, Cody Rhodes, joined the hall of villains as Sampson – a “stardust” dealer, who battled against the Green Arrow (Stephen Amell) in the handsomest fight in town. Felicity (Emily Bett Rickards) confessed her part in Haven Rock to Rory (Joe Dinicol). Diggle (David Ramsey) hallucinated Deadshot in the meanest audience trick, but wants to stay in jail for something he didn’t do, as penance for something he did – kill his brother. Lyla (Audrey Marie Anderson) was not having it, and went to get Oliver.
