Denial makes sense! That said, Rinzler's got tracking functions that offer a visual display of where people have been (glowy footsteps!), so there wouldn't be much question for him about it being "Nathaniel". (Not that he'd really take it to anyone else when he could murder problem-solve on his own.)

Would you want to do a thing with coin-stealing and confronting, or just handwave that attempts were made and backed down on (or something)?
