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.

After Barry Allen and Cisco (Grant Gustin, Carlos Valdes) reached out to Supergirl (Melissa Benoist) for help, Team Arrow, Team Flash, and the Legends joined forces to fight them.

Last week on Arrow, Oliver (Stephen Amell) recruited Team 2.0, hence the name. He was completely brutal to Curtis, Wild Dog, and Evelyn Sharp (Echo Kellum, Rick Gonzalez, Madison McLaughlin), and Felicity (Emily Bett Rickards) tried to talk some sense into him (she also had a moment where she looked sick). But Diggle (David Ramsey) is back in the military, but got framed and thrown in jail. Mayor Queen made a deal with AmerTek to fund a free clinic for his broken city. One of the reps got attacked by something with magic tentacles. Turns out that “Ragman” is a good guy and AmerTek is in bed with Tobias Church (Chad Coleman). Secret bankruptcies and what not. Prometheus is the new “Big Bad,” who is bigger and badder than Tobias Church. Who could it be?

Last week on Arrow, the team was reeling from the loss of Laurel (Katie Cassidy) – Diggle (David Ramsey) blamed himself, Lance (Paul Blackthorne) was in severe denial, Felicity (Emily Bett Rickards) blamed herself too, and Oliver (Stephen Amell) was stoic, but sensible. He is not going to let Darhk (Neal Macdonough) off the hook though. A fake Black Canary was running around town, marring Laurel’s work, but they stopped her easily. Oliver then announced Laurel’s superhero identity at her funeral to protect her legacy.
