Caitlin and Killer Frost finally managed to find some balance between their dual identities in Season 4, creating a symbiotic (even kind of loving) relationship.
Hopefully that path to co-existence will give us at least one scene of Caitlin and Killer Frost together, finally having a face to face meeting.
Don’t worry, though, the search for Killer Frost is a journey Caitlin will still be on in Season 5!
The Flash may have left us with the cliffiest of cliffhangers when it revealed Nora Allen and Iris (Candice Patton), but that wasn’t the only lose end from Season 4: What about Killer Frost’s (Danielle Panabaker) fate?!
