Adam had followed the CIA car with Troezen and then saw them go to the CIA base and drove off.
He parked the car and then got on a bus. The CIA would have obviously seen the car behind them the whole journey.
He got on for a few stops and got off, he was not sure where he was but he took another car and drove off until he found some street signs.
He turned around and went back to the CIA base. He parked a bit of a way back, but he didnt have long before they noticed him.
