Alexander waited patiently to see when Mathias would come out of the room he entered with a woman. He had almost missed Mathias as he had to slow down to not be seen but he had managed to witness him entering a room with a woman who lived in the brothel.
Alexander was quick to recognise parts of this brothel as they were forced through the day to sometimes work here during the time they were going to be sold. This was where Rose was to end up and all along, Mathias knew exactly where to find it.
Alexander gripped his sword. He was hoping that Mathias wouldn't betray him this way by hiding where he knew Rose to be. They wanted different things and that was fine. Mathias shouldn't be meddling hiding where Rose might be.
