The Flash season 7 episode 12 is still a few weeks away from airing on The CW. The superhero drama goes on hiatus, but it's going to bring more stories once it returns. Also, one of the significant characters will make his final appearance in the series.

The Flash season 7 episode 12 is titled "Good-Bye Vibrations" and it is going to be the last one for Cisco Ramon/Vibe/Mega-Vibe. Previously, it has been confirmed that Carlos Valdes is leaving the series after the seventh installment.

Cisco's exit was already teased to be coming sooner in episode 9, titled "Timeless." At the time, he was struggling with the gravity of Barry Allen's (Grant Gustin) plan. Then, he realized that it's time for him to leave Central City for good.

His decision also coincides with the plan of his girlfriend, Kamilla (Victoria Park), to relocate to San Francisco. This seemingly suggests that the couple embarks on a journey together and will start a new chapter moving forward with their future.

In The Flash season 7 episode 12, Cisco and Kamilla break the news of their departure to the team. The title "Good-Bye Vibrations," is also a reference to the former's power while serving the Central City as both Vibe and Mega Vibe. After all, he's been part of the superhero drama since it debuted.

Cisco has been a beloved member of Team Flash and was one of the longest-serving characters in the Arrowverse. He was introduced as a genius-level scientist helping Barry at S.T.A.R. Labs, before eventually becoming a heroic metahuman.

Meanwhile, the problem in The Flash season 7 episode 12 is that the team may not be able to digest Cisco and Kamilla's announcement. Barry, Iris (Candice Patton), and Caitlin (Danielle Panabaker) need to deal with the new version of Rainbow Raider (Jona Xiao).

Now, the OG Team Flash must join forces for the last time in order to save Central City. This means that Cisco would not leave them hanging and he will help them to defeat this villain, who was altered due to the Crisis on Infinite Earths.

During the first season of the superhero drama, Rainbow Raider was introduced and played by Paul Anthony. The gender-flip was the result of the Crisis on Infinite Earths, and Cisco may know how to defeat the new version after wandering around Earth-Prime.

The Flash season 7 episode 12 airs on Tuesday, June 8, on The CW. The episode is directed by Philip Chipera and written by Jeff Hersh and Kelly Wheeler.
