DC's Legends of Tomorrow has a Halloween-themed episode tonight that also connects with a major event from last season. The clip below contains major spoilers for the episode, so I won't start talking about it until after the image.
In tonight's episode, 'Phone Home', the team heads back to 1988 Ivy Town to try and figure out what anachronism kills young Ray Palmer (Jack Fisher).
The scene below shows the Ray we know (Brandon Routh) discovering that his younger self has befriended a baby Dominator. The Dominators were the race of creatures that all of the Arrowverse fought in last year's Invasion crossover event. The episode has a very E.T. feel to it, hence the episode title… though there are some other '80s references in the episode as well including a Delorean.
The team has to beat the clock to save young Ray before current Ray is permanently wiped out of existence. But these are the Legends, who caused the anachronism in the first place — so you know things won't go as according to plan.
DC's Legends of Tomorrow airs tonight at 9 p.m. ET on the CW.
