Despite partially covering 7375, the western wall of Room H-15, 7396 seems to be bound to 7375 as the mortar is connected between the two SUs.

If 7396 proves to be originally contiguous with the cylindrical feature 7394 at the center of the room, the ashlar inclusion would have to be a relatively late spoliated addition to the room, likely at least younger then the tufo slab floor 7320, 7337, and opus reticulatum wall 7374.
