Jimmy didn't wander far, just like in Portland before, he needed to see the aftermath, the key was whether there were any side effects.
Jimmy drove near Boston University, checked into a hotel, left his suitcase in the room, dealt with some personal matters in the bathroom, then called Winston, "It's done, the rest is up to you."
Winston: "Oh, OK, we'll talk when you get back."
Jimmy: "Yeah, do you have people here? Clean up the loose ends."
Winston: "Relax, we'll handle it."
Jimmy hung up the phone, checked the time, and immediately went out to find a mall and bought some clothes, disguising himself to blend in with the students around.
Jimmy wasn't that old to begin with, and being Asian made him look younger. After changing clothes, claiming to be a college student didn't seem out of place at all, so whether walking on the street or mingling around, it was effortless to blend into the crowd and not be noticeable at all.
