I don't agree with this. Sure, if they found one and keep it a secret. But they almost always tell others and that then directly affects voting strategy. They already leave viewers wondering "huh?" on occasion, thanks to the edit.And don't show people looking for idols, or whether they find them or not.
Wouldn't it be nice to have a genuine surprise at tribal council?
Then they could show a brief montage of how they found the idol.
