Top (Ashley Rickards) and Mirror Master (Grey Damon) will be reigning in Central City in the future. Meanwhile, Caitlin (Danielle Panabaker) will be hunted down by her own friends because of her new evil and powerful identity.

On the next episode of "The Flash" season 3, titled "The Once and Future Flash," Top and Mirror will be terrorizing all of Central City in the year 2024 when Iris (Candice Patton) has already been killed by Savitar.

As seen from the episode 19 trailer, the Mirror Master appears to be beating The Flash (Grant Gustin) to the ground. Although Top was nowhere in the trailer, episode 19 photos released by BuddyTV confirms the villain's return by Mirror Master's side in terrorizing all of Central City.

By the looks of Barry and Central City in 2024, along with the fact that Wally West (Keiynan Lonsdale) is in a wheelchair and can't be Kid Flash in the future, it appears that villains have taken over the city with Top and Mirror Master as king and queen of them all.

However, with present Barry, full of hope and strength, traveling to 2024, he will try to bring back the team together no matter how hard it will be.

Meanwhile, Caitlin will be hunted by The Flash and Vibe (Carlos Valdes) in the present now that she has become Killer Frost.

Previously on "The Flash" season 3, Barry had decided to unleash Killer Frost to save Caitlin's life. However, this decision might have led them to lose one of their closest friends.

"Back in 2017, the hunt for Killer Frost continues," the episode's synopsis reads.

Killer Frost also made an appearance in the trailer for episode 19, where she taunts Barry about the truth that led to Iris' death in 2024. This indicates that The Flash and his team will not be successful in trying to capture Killer Frost in the present.

"The Flash" season 3 returns with episode 19 on Tuesday, April 25, at 8 p.m. EDT on The CW.
