User blog comment:Eobard95/DOES SAVITAR HAVE AFFECTIONS FOR KILLER FROST?/@comment-3221148-20170520213350

I think it's the other way around. There have been hints of Caitlin's crush on Barry, if repressed due to the whole potential awkwardness. She was pretty bitter towards Barry specifically getting a "happy ending" with Iris during her first Killer Frost incident. She could see it as a chance to start things anew.

Savitar, I doubt loves anyone, anymore. He expressed regret over having to kill Iris to stay alive in his personal timeline, but that's it. All the self-hatred regarding having to do that is likely to keep him emotionally distant from anyone, Caitlin included. I think he'd be... insulted, by the very suggestion that he could love anybody ever again, lest of all the woman who assisted him in killing his true love.
