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

11. Will Killer Frost Change Alleigances?

Ever since the Season 1 finale teased Killer Frost, fans have been desperate to meet the villainous version of Caitlin Snow, and the promotional material for this episode was pretty heavy on that aspect of things, alongside the bad guy version of Firestorm, Deathstorm (and not, er, Darkstorm, as I originally wrote...). Thankfully, they didn't disappoint. It reminded me a bit of Buffy episode The Wish, which featured Willow and Xander as vampires. Killer Frost and Deathstorm were similarly, gloriously hammy, and you could tell that Danielle Panabaker in particular was having a lot of fun, really enjoying the opportunity to cut loose. Come the end of the episode, though, Deathstorm is dead, and things don't look too great for the relationship between Killer Frost and Zoom. Will she continue to work with him, simply go into hiding, or could Team Flash actually convince her to turn good, and help them in their fight against Zoom? Given he killed the person she loves, it could well be on the cards.
