Thomas Hunter meets Chalise

So there  is an event that is described in both the book Red and Infidel. (I had been listening through the circle trilogy unabridged on my drives this summer and picked up the lost books off the book shelf to try to catch up in that series). This event is Thomas Hunter meeting Chalise. I am familiar with the circumstances of their meeting in the story of Infidel since I am currently reading it, but I am trying to remember the circumstances in the other story. For some reason, I think they have some discrepencies. Can anyone recall how Thomas runs into Chalise in the Circle trilogy? (When he introduces himself as Roland the scab)
