This week, The Flash returns from its midseason hiatus with familiar foes resurfacing across post-"Crisis on Infinite Earths" Central City.

In new official stills from "Love Is a Battlefield," Barry Allen and Iris West-Allen attempt to have a romantic date night, only to be interrupted by Barry's old enemy Amunet Black. In addition to Katee Sackhoff's return, Damion Poitier will reprise his role as Season 5 villain Goldface.

According to the official synopsis for "Love Is a Battlefield,"

LOVE IS IN THE AIR -- Barry (Grant Gustin) and Iris (Candice Patton) plan a romantic dinner for Valentine's Day but their evening is interrupted by an old foe -- Amunet (guest star Katee Sackhoff). Meanwhile, Frost (Danielle Panabaker) gets into the holiday spirit and attempts to help Allegra (guest star Kayla Compton) reconnect with an old love. Sudz Sutherland directed the episode written by Kelly Wheeler & Jeff Hersh (#611). Original airdate 2/11/2020.

Katee Sackhoff teased her return as Amunet Black this past November, after the villain temporarily worked with Killer Frost while Caitlin Snow struggled with her own inner darkness. Given Amunet's abilities to manipulate metal, her alliance with Goldface may be a one-sided one.

Returning Tuesday, Feb. 4 at 8 p.m. ET/CT on The CW, The Flash stars Grant Gustin, Candice Patton, Carlos Valdes, Danielle Panabaker, Tom Cavanagh, Jesse L. Martin, Danielle Nicolet and Hartley Sawyer.
