Flash TV Talk 5X06 The Icicle Cometh

Barry, Cisco, and Caitlin find her father Thomas and take him to Star Labs. Meanwhile, Ralph and Cecile continue their investigation on Cicada's identity by looking into a FEMA camp set up after the satellite exploded. Sherloque, Iris and Nora choose another route by looking for the satellite’s core. Caitlin and Thomas go on a walk to reconnect but are interrupted when Thomas faints and his arm starts turning into ice. Caitlin takes her father back to Star Labs where he reveals to her the origin of her powers. Cisco, suspicious of Caitlin’s father’s story, teleports back to Thomas' base where he discovers evidence that Thomas isn't Caitlin's real father. Caitlin refuses to believe Cisco until she sees the truth about her father with her own eyes when Thomas’ alter ego "Icicle" takes over. Just as Team Flash confront Thomas, Killer Frost returns and defeats Icicle. FInally, it is revealed that DeVoe used Dominic Lanse/Brainstorm's powers to mentally block Caitlin from summoning Killer Frost, while Cicada, despite his previous injuries, reveals the wound he received from the satellite is making him stronger.
