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, Savitar kept messing with Wally’s (Keiynan Lonsdale) mind. Julian (Tom Felton) reluctantly went under so Barry (Grant Gustin) could talk to Savitar. Caitlin (Danielle Panabaker) confessed she kept a piece of the philosopher’s stone, which turned out to be a good thing. As long as it wasn’t whole, Savitar was trapped in the speed force. Unfortunately, Wally threw the other piece in, freeing Savitar and trapping Wally. Jesse (Violett Beane) turned to HR (Tom Cavanagh) for dad comfort. Barry and Iris (Candice Patton) got engaged, then unengaged.

Last week on The Flash, Grodd (David Sobolov) and his army came to Earth-1 from a breach that Gypsy (Jessica Camacho) made because of mind control. Although it looked completely hopeless that Barry (Grant Gustin) could defeat him without killing him, both Iris and Harry (Candice Patton, Tom Cavanagh) pep-talked him into another way. That way? Tagging Solovar (Keith David) in to defeat Grodd and take the army back to Earth-2. Jesse (Violett Beane) decided to stay on Earth-1 with Wally (Keiynan Lonsdale) and give it a go. Gypsy smooched Cisco (Carlos Valdes) goodbye.

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 time on The Flash, we saw a bit of Julian’s (Tom Felton) history, which basically explained the Alchemy/Savitar situation with something called the Philosopher’s Stone. Earth-3’s Jay Garrick (John Wesley Shipp) was supportive (almost like a dad), with wise words and a suggestion to get rid of the Philosophers Stone (oh yeah-fixed Julian and “fixed” Savitar), of throwing it in the speed force. Barry (Grant Gustin) accidentally ran 5 months into the future and watched Iris (Candice Patton) die at the hands of Savitar. Barry gave Iris an awesome apartment for Christmas.
