Or Grace herself, I suppose, but more I was thinking of Harold and Reese trying to figure out if this new guy is bad, good, in between, and wresting with the desire to get him the hell away from Grace any which way. Also, Harold battling the urge to reveal himself, Reese "subtly" (as subtle as he gets) intimidating the hell out of the guy and shuttered disapproval of Grace's move onward (with or without a conflicting urge to hope she DOES move on should the story go Rinchy, which I have a personal thing for), the both of them maybe trying to keep Carter and Fusco from figuring out Grace's connection, and Bear pulling things out of Grace's house that smell like Harold.

Um. Any or all of that--forgive if this is a prompt already that I missed.
