Final episode in the first season of this new show, which is the latest in the recent Arrowverse series, that also includes The Flash and Arrow. It all kicked off when time-traveller Rip Hunter traveled back 150 years to put together a dream team that would save mankind. Your usual superhero shenanigans essentially.
In tonight's finale, with no clues as to Savage, Carter and Kendra's whereabouts, Rip decides it's time to return the team members to their normal lives, but it's not long before they decide that they cannot leave their mission uncompleted. They return to the Waverider and quickly realise that Vandal Savage (what a name) is in France in 1944 and is using Kendra and Carter's blood to unlock the technology he needs to erase all of history. Well that does not sound good.
