When we see the town within our sight, we know that we had to part away with Tane, it would just bring him trouble if we were sighted by the guards now. Tane will surely get arrested as well, he was nice to use, and if we don't want him to be involved in our personal matter.
Vicar then stops at a point and Tane noticed that Vicar stops moving. He asks Vicar why he stops, the town was just in front of us. We didn't think a good lie for this situation, Tane would suspect something was going on behind him if we didn't manage to convince him.
"Umm, We had some stuff to do first.. you could go ahead Tane."
"Some stuff? I thought you want to go to town first."
"We did want to go there first, but we have to do something important."
"Can I know about it?"
"No! You can't... it something personal." Vicar stutters.
