The Flash Season 2: 13 Big Questions We're Asking After 'Welcome To Earth-2'

10. Could Earth-1 Caitlin Become Killer Frost?

As mentioned in the last entry, Panabaker really cut loose with her performance as Killer Frost, and it was really fun to watch. It's no surprise that she clearly loved the opportunity to play Killer Frost, because aside from her being a good character anyway, it represented a nice change of pace from doing, well, nothing back on Earth-1. The show has expanded its scope a bit this season, and Caitlin has been the victim, with no real storylines or major part to play, instead lumped with Jay Garrick and anything she does revolving around his own plight (something not helped by the fact that has been a pretty weak arc). Hopefully she'll get more to do in the future, but also I hope they'll find ways to have more appearances from Killer Frost beyond this two-parter. Could we even get to see the real Caitlin become a full-time villain, going up against Barry and Cisco for a number of episodes, with actual stakes rather than knowing its a doppelgänger? Unlikely, maybe, but here's hoping anyway.
