John Meehan

John Meehan arrives in Debra Newell's life as an answer to loneliness: an anesthesiologist who is attentive, generous, and endlessly patient with her skepticism. He says exactly what she needs to hear, moves fast toward commitment, and treats her family's wariness as an obstacle to be charmed rather than a warning to heed.

Eric Bana plays him at a steady, reassuring register that never tips into obvious villainy, which is the point — the show needs you to understand why Debra believes him. That warmth with something faintly off underneath it is unnerving precisely because it's so plausible, so ordinary, so easy to want to trust.
