The Flash Season 2: 10 Big Questions We're Asking After 'Back To Normal'
5. Will We Learn More About Caitlin's Family?
In that scene with Caitlin and Killer Frost, there was one intriguing issue brought up before the latter's untimely demise: that of their family.
Caitlin's personal life isn't one we've really explored beyond her romantic relationships, but as it turns out here she has a horrible, overbearing mother, regardless of which Earth she's on.
The more interesting point, though, is that Killer Frost had a brother, while Caitlin says she didn't. That's not the kind of plot point they'd just drop in there randomly, surely? Is this suggesting that there's more to the Snow family than we - and perhaps Caitlin - know about? And just when will we find out about it?
