Jack followed Hasimu to the village hall he had searched earlier. Jack wondered what the orc was doing there when a siege was happening right outside his village.
The two soldiers following Hasimu stayed guard outside while Hasimu went into the village hall. Jack followed closely without touching those soldiers and entered before the entrance door closed.
Jack continued to follow Hasimu who went to the main hall and removed a carpet from the floor, revealing a trap door.
When Jack was going through this building earlier, he was in a hurry. He didn't realize that he had missed that trap door. He also didn't come close enough for his monocle to detect anything.
Hasimu opened the trap door and went in. Jack quickly followed.
