Cold to the Touch

Caitlin had started working on a way to fix herself and Killer Frost. The only problem was that she had started working on it before they defeated DeVoe. Now that they were free of the Thinker, she was still working on her problem alone, but without the proper help, the serum could kill her.

Even though Caitlin's secrets are potentially dangerous and life threatening, she is not the only one hiding something. Barry is also keeping secrets of his own, more minor secrets. Putting on a brave face for the team and his daughter from the future, he hides the fact that he and Iris as fighting more and more often. With a West-Allen divorce on the horizon, he can't seem to hide his newly found budding feelings for one Caitlin Snow.
