TVLine released some preview details on certain shows, including The Flash.

Judging by the title of Episode 10, “Revenge of the Rogues,” Barry won’t get a breather after his battle with Reverse-Flash. Wentworth Miller warns that as Captain Cold teams with Heat Wave (Prison Break’s Dominic Purcell) to stop the speedster, the foes “aren’t friends, but they do have a kind of intimacy.” Cisco – who’s getting a brother! – will face Cold’s fury when the villain’s sis, Lisa Snart (Tomorrow People’s Peyton List), uses her wiles on S.T.A.R. Labs’ geek boy. Meanwhile, Caitlin – reeling from her “dead” fiance’s reappearance – may be led down a questionable path. “There are some moments – maybe she goes back to a bar? maybe she makes some bad decisions? – that are really fun,” Danielle Panabaker teases. Also on tap: Star Wars’ Mark Hamill reprises his ’90s Flash role as The Trickster; Grant Gustin sings (courtesy of the Pied Piper?) and (accidental) time travel makes its debut.

RETURN DATE: Tuesday, Jan. 20 at 8/7c (The CW)
