In Haunt 88, what happens when the Cat omen is the trigger and the traitor cannot hold the Cat?

Question

Accepted Answer

The Traitor's Tome and Secrets of Survival override the rule against dropping companion cards. The Tome tells the traitor not to hold the Cat and the heroes get instructions for the Cat card, so the haunt proceeds rather than being cancelled.
