In a clip from tonight's episode of Legends of Tomorrow, Rip Hunter learns why the Time Masters are backing Vandal Savage. If their prognostication is current, it is likely a spoiler. But it is a fun one for people who love the wider breadth of the DC Universe.
I want to watch a show about what happens in 2175. But I guess I've already seen versions of it in a comic book miniseries and the animated Justice League.
Legends of Tomorrow airs Thursdays on The CW.
