I'm not sure I understand Fox's plan of burning off its last three Season Four Houses in the space of a week, but at least the close succession of Sunday's "Frozen" and tonight's "Don't Ever Change" allows House fans to meditate on the show's eternal theme, as stated plainly in the titles of both episodes.
The POTW (patient of the week) is a Hasidic Jew, played by Laura Silverman, who collapses on her wedding day, demonstrating a rash of SUSs (seemingly unrelated symptoms) that involve a lot of blood in bodily fluids where blood shouldn't be. The kink in her circumstances is that she's only been deeply religious for a short time; prior to converting, she was a fast-living music producer, hooked on the heroin and the sex. So naturally, House assumes that the person she presents herself as now is pure put-on, and that her illness is part of her true self's attempt to kill the devout phony she's become.
Meanwhile, following up on the surprise ending of "Frozen," House thrusts himself into the middle of the romance between his long-suffering pal Wilson and his ex-applicant Cutthroat Bitch, because, as he puts it, "I don't see that I have any choice." Determined to prove that CB is only cozying up to Wilson so that she can get back on the diagnostic team, House grills her and baits her, waiting for her to crack.
But no dice. And in the A-story, Silverman also fails to crack. She adheres to her faith even when it means refusing surgery before sundown, because her faith has given her life meaning, and she doesn't want to die having rejected it. Final result? House's own devout faith–that "people don't change"–has been tested. Yet again.
Look, this was a decent episode in terms of its mystery–which had a neat, and touching, resolution–and it was great to see Silverman in a dramatic role. But none of the conflict between House's skepticism and Silverman's belief really came to much, and in the end, the philosophical questions weighed by the episode felt a little stale…nothing this show hasn't covered before.
