Here’s what’s happening in the world of television for Monday, January 15. All times are Eastern.
The Gifted, two-hour season finale (Fox, 8 p.m): We’ve spent much of The Gifted’s first first season with the mutants on the lam, but in this two-part finale, Polaris (Emma Dumont) has had enough of the running—from Sentinel Services, and from the myths of her similarly powered forebears. “This will change everything,” Eclipse (Sean Teale) warns in a preview, but Polaris is just over this shit. The final season-one episodes, “eXtraction” and “X-Roads,” air back to back, but one of reviewer Jesse Hassenger’s mutant powers is being able to sit still for 120 minutes (give or take) at a time, so it’s nothing he can’t handle.
