Weird Situation.

Jarkon became silent while he thought to himself, "Such pitiful fellows."

They are not like him. They have taken this mission very seriously. That's why they are worried that the security forces of a plane will delay them from getting close to the planar portal. 

A planar portal can not be accessed by just anyone. It is the one sure way into a plane so the plane will try to protect it and limit access to it. That's why some people won't want them to get anywhere close to the planar portal even when they promise that they don't want to use it or that they mean no harm. But Jarkon doesn't mind. The delay just gives him more time to enjoy the sights. 

They were frustrated with the delay and he tried to help them out but they were not like him. They didn't even want him to express his wayward feelings about the mission to them. They know that he is rebellious but they don't want to hear his rebellious thoughts.
