Killer Frost is Coming Back For Iris' Bachelorette Party on 'The Flash'

We’re not sure if Killer Frost will be the life of the party or the party pooper when she returns for Iris’ bachelorette party on The Flash.

However, Danielle Panabaker is teasing that Iris and Caitlin Snow’s alter ego will connect on another level.

“When Killer Frost shows up, Iris has a lot of compassion for Killer Frost and a lot of compassion for Caitlin,” Danielle told EW.

“[It] is pivotal in helping Caitlin reconcile herself with her past and some of the mistakes that Killer Frost made.”


Iris’ bachelorette party will also have some other guests there — like Felicity Smoak.

The Flash airs Tuesdays @ 8PM ET/PT on The CW.
