The Flash - Season 6, Episode 09: Crisis on Infinite Earths: Part Three
Trailer
Season 6 follows new events, with Crisis only a few weeks away. Now, Barry tries to set up a team member for Team Flash for life where he tries to catch a hideous world, and Ralph reveals the secret of the family that will change the course of events. Meanwhile, Barry and Iris are still trying to face their fate in order to deal with the tragic loss of their daughter Nora.
The writers have missed a few easy to achieve marks that haven't made the story as effective, but the crossover remains a very fun and unpredictable effort.
This episode not only had to deliver 100+ episodes worth of emotional and narrative payoff, it was also the climax of the single most ambitious crossover in television history.
