As Inigo searches the camp, he finds nothing. No food, no bedding, not medical supplies, no sign that life had ever existed here aside from the tents and torches.
As Melissa and Lan watch the camp, they see only one figure, hobbling around with the help of a large stick. He seems to be searching the camp for something. However, neither Melissa nor Lan can see the figure properly from this distance.
Shard continued to sit against the wall, clutching his head. Something wasn't right. If his captors wanted information, they would have someone here to watch him, so they could the info from him as soon as he woke. If they wanted to enslave him, he wouldn't still have the remaining clothes he did. If they were threatened by him somehow, they wouldn't have let him live. And why taunt him? Sure, maybe that was just for fun, but there are safer means of doing so than having his gear nearby, so they must be trying to make it personal.
Only two possibilities remained; Either someone he made enemies with wanted revenge, or he knew something that endangered his captives. However, even those didn't seem likely. He never let his enemies live, and only ever took the minimum amount of info required to finish a job.
Maybe he was just overthinking it.
