Based on a number of factors (e.g. the presence of threshold 5566), we can discern that an E-W wall should have been here forming the rest of the southern boundary of Room 16 and the northern limit of the central courtyard 5550 (this would have been the eastern extension of 5574). The lower course of 5574 doesn't seem like it would technically have had a physical relationship with the robbed wall because of the interruption of N-S wall 5551 but the upper courses might have. This was the reason that the cut was documented as the robbery of wall 5574.
