I do wonder what the long term plan is with Caitlyn and KIller Frost. She is so much more interesting as KF that curing her would be be a huge disappointment. I do not think her using her powers for good and becoming a hero would work. So much of what makes her performance interesting is the villainy. Would be rather dull to have her go back to mostly giving techno jargon but now with white hair. This show is still about the Flash. Even if Caitlyn becomes an Ice powered hero she would only occasionally use her powers. Similar to how rarely Cisco is full Vibe. Most of the time is role on the showis still as the tech guy.
