You know, sometimes these things just happen. But what if they don’t? What if a mole is to blame here? That’s the theory chewed on by Dean (Rob Lowe) — and received skeptically by Stewart (Fred Savage) and Claire (Natalie Morales), the latter of whom is all but accused of such a treacherous act by Dean. Check out a scene from “The Curious Disappearance of Mr. Donovan,” which airs tomorrow night at 8:30 p.m. on Fox. Of course, there will never be a greater mole than this one.
