She then starts ranting at Gus for running off without telling her and putting her in this position. Dinah then veers the conversation back to Mallet.

Mallet has theories: 1) Gus killed Alan and disposed of the body--No, he wouldn't kill his father 2) Gus stashed Alan away in a psychiatric hospital--No, too far-fetched. 3) Maybe it wasn't Gus who got the jump on Alan--maybe Alan got the jump on Gus. In other words, maybe Gus is dead.
