'The Flash' Season 2 SPOILERS: Twitter Reacts Danielle Panabaker's Caitlin Snow/Killer Frost!

The CW Network continues with Season 2 of The Flash. With the identity behind the super-villain Zoom (voiced by Tony Todd) revealed, Twitter had lots to say about Caitlin Snow  meeting Killer Frost (both played by Danielle Panabaker) in Hunter Solomon (Teddy Sears)'s lair.

In our previous recap, Caitlin revealed Jay's name was actually Hunter Zolomon, a serial killer turned metahuman back on Earth-2. Even though the scarlet speedster tried to trick Hunter, it was not enough to stop Zoom from stealing Barry's speed force. With Barry back as an average human being, Zoom kidnapped Caitlin and took her back to his world.

In our recent recap, Barry had to live his everyday life as a normal person, but that didn't mean his superhero days were over. With the crime rate rising in Central City, Harrison Wells (Tom Cavanagh) was abducted by Griffen Grey. As the scarlet speedster recused Wells, Caitlin found herself face-to-face with her doppelgänger, Killer Frost. In order to save Caitlin, Hunter had to stab Killer Frost to death. In order to rescue Caitlin and restore Barry's powers, Wells has to create the particle accelerator explosion once more.

In an interview with TV Line, showrunner Andrew Kreisberg explains why Killer Frost had to die, ""We loved what Danielle [Panabaker] did with [Killer Frost], so when we were designing this episode and we had Zoom kidnap Caitlin, it seemed like a fun thing to do to be able to have the two of them together. To have Caitlin actually experience time with her [doppelganger] gave us an opportunity to sort of deepen both characters. But ultimately, she had to go. Like even she said, the only reason he had to keep her alive was she was a living remembrance of him caring about [Caitlin]."
