I believe I said something to this affect in some tags ages ago, but I absolutely think jon giving jess tyrell the name of his workplace was a deliberate attempt at getting caught. parsing some timeline stuff, he took his first three victims in the first three weeks he was out of hospital, but then jess was his first after two months of nothing. I think he tried to stop, realized he couldn’t keep it up, so (maybe subconsciously) set a trap for himself while also making sure he’d be on a boat to norway for the immediate fallout.
