Lipsha went out to his new car and drove it off. Along the way, he started hearing some thumping. He ignored it at first.
However, eventually he stopped as the thumping got more insistent. When he opened the trunk, he found Gerry hidden there, almost out of breathing air.
At Gerry's request, Lipsha drove him up toward the Canadian border (this time with Gerry in the car, natch). Along the way, they chatted. They talked about whether Gerry was actually guilty of killing that trooper, but Lipsha stops short of revealing exactly what Gerry told him.
