Dr. Eric Foreman

Dr. Eric Foreman is a neurologist on House's diagnostic team, brought in for his sharp instincts and a resume that includes a juvenile record he'd rather leave buried. He's disciplined, ambitious, and wary of turning into his abrasive boss, even as he can't help absorbing his methods.

Foreman is the show's conscience, the one who keeps score of how far House's brilliance tips into cruelty. Omar Epps plays that tension quietly, letting irritation and admiration sit on his face at once, so his slow, reluctant transformation into a diagnostician of House's mold feels earned rather than written.
