Alistair's mostly gotten the hang of Skyhold's layout by now. (It helps that the landscape doesn't shift and warp every couple of hours.) So: up the stairs, along the walls, to the tower he knows houses Cullen's office.

If the man's anywhere, he's probably going to be here; if he's not, well. More walking will do him good.

Tentatively, he raps his knuckles against the door.
