Since there was still plenty of time, Jimmy didn't plan to leave immediately. Instead, he spent the day resting at home and drove back his car from the parking lot at Teterboro Airport, taking some time to familiarize himself with the roads in Portland and Boston as much as he could for convenience later on.
Jimmy took out the identity documents Tom had prepared for him from the safe, looked at the handgun, and eventually chose Tom's P226 since it had a silencer and was more suitable for use.
Carrying some cash, Jimmy left a message for Nia and then left the apartment.
The identity documents Tom gave to Jimmy were real. He had already verified this shortly after obtaining the warehouse information, so using this identity was no burden for him at all.
