Informational overload! And, spoiler alert! Anyone who wants to go into this week’s ‘Arrow’/ ‘The Flash’ crossover without any prior knowledge stop reading now!

To promote the epic 2 night cross-over event (which also seems to be a weird kind of back-door pilot for ‘Legends of Tomorrow‘), the CW has released the synopsis’s for both episodes, as well as a new featurette about the crossover’s characters, and released a clip from the special, wherein we meet Carter Hall as he explains Vandal Savage’s connection to him and Kendra Sanders. Hopefully, this will all be enough to tide us over until ‘The Flash’ tonight!

Here’s the synopsis for ‘The Flash’ half of the two night event:

“In its second major crossover event with “Arrow,” Vandal Savage (guest star Casper Crump) arrives in Central City and sets his sights on Kendra Saunders (guest star Ciara Renée). After Vandal attacks Kendra and Cisco, they turn to Barry for help. Realizing how dangerous Vandal is, Barry takes Kendra to Star City and asks Oliver and team to hide her until he can figure out how to stop Vandal. However, things quickly go from bad to worse when a man with wings AKA Hawkman (guest star Falk Hentschel) shows up and flies off with Kendra. Meanwhile, Harrison develops a serum to make Barry run faster and asks Jay (guest star Teddy Sears) to test it out.”

And here’s the synopsis for the ‘Arrow’ episode:

“Oliver and Barry Allen take Kendra Saunders and Carter Hall to a remote location to keep them hidden from Vandal Savage while they figure out how to defeat him. Malcolm arranges a meeting between Vandal, Green Arrow and The Flash that doesn’t go as planned. Meanwhile, Felicity, Thea, Diggle and Laurel work with Team Flash to come up with a weapon powerful enough to destroy Vandal Savage.”
