The Flash: 10 Biggest Questions We Have For Season 6

10. Will Caitlin's Mother Meet Her Icy Alter-Ego?

The troubled relationship between Caitlin Snow and her mother, Dr. Carla Tannhauser, has been one aspect of the show that just doesn't get as much attention as it needs. That being said, Season 5 did devote a little more time to their story than usual as the pair finally managed to patch up some old frosty wounds. But the situation that brought them together could end up being the very thing that causes even more trouble between them in the future.

After kidnapping both of them, Icicle (a.k.a. the icy alter-ego of Thomas Snow) attempted to make Carla like himself and Caitlin by giving her a frostier personality and, although The Flash managed to stop the process before it went too far, it appears that he wasn't entirely successful in doing so.

After testing her mother for residual metahuman DNA, Caitlin revealed that the liquid she used didn't turn white and, as a result, was able to confirm that she was unaffected by Icicle's experiment. However, when the pair left S.T.A.R. Labs, the liquid did indeed turn white.

Of course, this left viewers wondering if Carla will now develop an inner ice queen and, if so, will she be redeemable like Killer Frost, or will she have more of a penchant for destruction like Icicle? Let's hope we find out in Season 6.

Gives a whole new meaning to a cold relationship, doesn't it?
