Back at Star Labs- Cisco, Caitlin, Wally, Jesse, Eddie, and Iris have been planning a way to take down Future Flash without Barry. They have also been protecting the city for the past month, however to Barry and Laurel its been over a year due to time travel on Earth 38.
Barry and Laurel finally come through the breach on Earth 1, they reveal to Team Flash they went to Earth 38 and stayed there for a year, then came back in time the same way Wally and Jesse did.
Cisco: Great so Earth 3 is off limits because Barry said future Jay from May 24, and that is in two days, and Earth 38 is off limits for a year because Barry and Laurel have been there for a year straight.
Caitlin: There are infinite Earths Cisco, don't worry as long as we stick to the plan, its all good.
Wally: Actually, Jesse and I were just talking and we decided to move to Earth 38, in the future being right when Barry and Laurel left, if that is okay with you?
Barry: Yeah, but once you go to the future, you won't be able to come back here.
Jesse: Actually technically we can but-
Barry: Nevermind actually lets not mess up the timeline of another Earth, save the future for the future. Right now we need to stop Future Flash. What's the plan wait no don't tell me, anyways whatever the plan is, after tomorrow future flash is going to come after Laurel. What do we do exactly?
Cisco: What we get is that Future You, came back in time to prevent the murder of Wally West but when he saved him, he realized he was being erased from existence and now, he wants to end the life of Laurel instead, so he can be born.
Suddenly, Future Flash pops into Star Labs.
Laurel: OH MY GOD!
Future Flash: Looks like you think you can beat me, I will take my woman for now.
Future Flash runs with Laurel, Barry goes after him. They go across the city and around the world with Future Flash carrying Laurel. They end up at Lian Yu. Where Oliver is there now with Prometheus however they're on the other side of the island.
Barry: Please don't do this, don't do this!
Future Flash: Now, finally I am free of you!
Laurel: Barry, I love you.
Barry: No Laurel don't say that alright, you're going to be okay!
Future Flash attempts to stab Laurel however suddenly when the blade touches her it bends, and the island explodes (this is the same time Prometheus on Arrow shot himself and the island exploded).
Future Flash: What the.
Barry is surprised and does not understand what is going on.
Laurel taps her neck, and reveals herself to really be Supergirl in disguise. She punches future flash which knocks him out.
Barry: Kara. How did you?
Kara: You helped me defeat Reign, what you think I won't return the favor?
Barry: Thank you.
Kara: Anytime. Now, I have the breach device with me, all I have to do is set the time and Earth to my Earth and 2018 right?
Barry: Until next time.
Kara heads back to her Earth, Future Flash then runs off. Barry chases him and Future Flash opens breaches to different Earths which they run on until they get to Earth 1 again. Barry remembers that when he defeated Zoom, he summoned the time wraiths. So he goes back in time to Lian Yu and hides there to see the Future Flash's attempt to kill Laurel, and then goes back to the present to chase Future Flash, which causes the real Black Flash to come after Future Flash.
Future Flash gets taken into the Speed Force, in a prison that Barry creates for him. Before going into the breach, Barry knocks him out and then Future Flash is sent into the Speed Force to be punished.
Barry goes back to Star Labs to reveal to Laurel, Cisco, Caitlin, Eddie, Iris, Wally, and Jesse that Future Flash has officially been defeated for good, by summoning the Speed Force to imprison him.
Wally and Jesse then go back to Earth 2, and Eddie and Iris reveal their engagement and decide to go off on a vacation. Later that night, Barry shows Laurel their new home as he asks her to marry him, they then kiss passionately. Afterwards, their apartment is disrupted by a huge noise outside their door, and suddenly a speedster comes in.
Bart: Mom, Dad!
The face on Barry and Laurel's face is shocked and curious.
Barry: Wait who are you?
Bart: My name is Bart, Bart Allen. I am your son, from the future.
