Yes, in fact i think Killer Frost will be Season 4's main antagonist. However unlike Arrow, Flash will eventually have Killer Frost reform. (hopefully they will do it the Rebirth way and Supergirl helps reform her) Why do i think Caitlin will be reformed, but Black Siren won't? Because Black Siren doesn't have an alternate personality to blame on her murder spree.

Mick is part of the Legends and Rip has different moral grounds then other heroes in this universe.
