Linh just come clean with the full story if you want sympathy.

He brought 2 characters to the BCNM. He had agreed to give up one of his shanks in exchange for being able to lot the tongue when it dropped. After Pewpew's run, which went smoothly, he went and they failed because Pewpew left the bcnm at 10% thinking they would be fine to finish without him. When Linh was asking if he had to give up his other shank to lot the tongue, the Leader rushed into the next bcnm before answering him. At this point most of us would be upset if not suspicious. So yeah he didn't want to have to give up his other shank if the tongue didn't drop since Pewpew had caused them to fail Linh's first run. IDK if Pewpew did that on purpose, but he was in Jueno selling King Behemoth runs the next day so I wouldn't put it past him to try and monopolize the market.
