'The Flash' season 6 to explore Danielle Panabaker's Caitlin Snow aka Killer Frost in ways 'we haven't seen before'

By the end of the episode, after helping Barry stop the black hole, Caitlin agrees to the idea of letting Frost take over and transforms (sort of permanently) into her alter-ego

'The Flash' season 6 premiere opened with the team coping with the loss of Nora (Jessica Parker Kennedy) in their own ways and Danielle Panabaker's Caitlin Snow aka Killer Frost was no exception. There was a new dimension that was explored for Caitlin and Frost's relationship in 'Into the Void'. 

Caitlin's storyline took off when she hears of the death of Rachel Rosso, a doctor, and mentor in her medical school who eventually helped her get a job at STAR Labs. She meets her son Ramsey Rosso (Sendhil Ramamurthy) at the funeral. Soon after, the black hole, courtesy Chester P. Runk opens outside CC Jitters and Caitlin's powers fail to come to the fore. While this becomes a cause of concern, Ralph Dibny (Hartley Sawyer) deduces that this is the result of Frost having issues centering around death. 

This theory was later proved true when Frost confirms this with Ralph. She also wonders if Caitlin is ready to let her take control of the shared body. By the end of the episode, after helping Barry stop the black hole, Caitlin agrees to the idea of letting Frost take over and transforms (sort of permanently) into her alter-ego. At the moment, we don't know if this permanent.  This transformation though will still affect the duo as they will eventually take on Ramsey's Bloodwork. And then there's the 'Crisis' to deal with.  Given how the character of Killer Frost has evolved over the years, this evolution seems to make complete sense. 

This move just goes on to prove showrunner Eric Wallace's thoughts on Catlin Snow's character arc in season 6.  "Killer Frost is going to explore her humanity in ways we haven’t seen before — and sometimes that means her being on the team more than Caitlin." (According to TVLine). That doesn’t mean Caitlin is gone — obviously, she is integral to the story because she has the connection to our Big Bad, Bloodwork (aka Dr. Ramsey Russo)," he shared.

He added, "But some of the fun, some of the sadness, and some of the mysteries from Killer Frost's past that we haven’t really been able to deal with, now we can."

Only time will tell what's in store for Caitlin as the series progresses.

'The Flash' airs Tuesdays at 8 pm on The CW.
