Ambrose swipes the card again once Luke's gone through, and follows after him, walking up to the map and checking which station they're on. There only seems to be one line from this station, and the different trains on it don't seem to split route while on Manhattan anyway. Doesn't matter much which one they get on then. Ambrose heads to the Southbound platform.

"We're going downtown, that much I know. How far, and if we'll have to change someplace, I'll have to find out along the way," he tells Luke. Hope Luke doesn't mind wasting half an hour with Ambrose.
