In times of chaos, it's not difficult for anyone to slip into a place relatively unnoticed. Normally he wouldn't bother, would see that chaos and move in the other direction. Normally he's following no particular path, and for the most part problems that are not his problem are easily avoided.

This one is his problem. His problem is in the form of a 5'8" grey-haired man standing in the middle of a group Roland would want to keep an eye on even on a regular day. He tries to stay unnoticed as he edges closer, but it's difficult to look like a random bypasser when he can't keep his eyes off his friend and the crowd surrounding him. He finds himself sending out his mind a little, trying to feel around the edges of their thoughts to see how likely that the crowd is going to become a mob.
