We’re 2 weeks removed from the season five finale of The Flash on The CW at the time of this writing. It was a finale that saw another change in the timeline due to the interference of Nora West-Allen all season long.
As a result, the Reverse Flash is back on the loose, Sherlock went back to his earth, Nora disappeared, and Cisco decided to take the cure and remove his Vibe powers.
Not only is Cisco a big part of Team Flash using his scientific knowledge and creativity (plus he’s the funniest character on the show), but his meta-human abilities to open dimensions were helpful for the entire team.
Now that Cisco is a regular human again, who will be able to step in and fill his shoes as an additional meta-human on the team?
Dr. Carol is Caitlin Snow’s/ Killer Frost’s mother. We were introduced to her while her relationship was strained with Caitlin. She kept the meta-human status of Caitlin’s father, Thomas Snow, a secret. Ultimately, Thomas tried to turn both Caitlin and her mother into frost meta-humans for good.
We saw Caitlin and Carol reconcile before the end of season five. But, we also find out that Carol now has meta-human DNA in her blood due to the efforts of Thomas Snow.
Dr. Carol could possibly enter Team Flash as an extra brain to assist with dissecting meta-human issues and as she realizes her meta-human abilities, she will be able to join the team in the field.
Maybe her name could be called Mother Frost.
My other suggestion is Harrison Wells. Every season they find a way to bring his character back into Team Flash. So perhaps they can do it again. But then again, bringing Dr. Wells back again will only fill the void that Sherlock Wells left.
So maybe no one can fill Cisco’s role and we’ll just have to deal with his absence and look forward to new additions to the team that we haven’t met before.
