"Oh, there is an hour of daylight remaining at least! Lets keep following further. There's always another good campsite around the next corner."
When the rest of the group agrees that it is getting to dark (whether now or further down the road), Planus says, "Fine." He droops his head for about a second and, finding sulking boring, says, "I'll find a good campsite." He starts searching the immediate area for a campsite out of the wind with some cover where we can see anyone approaching before they can see us. Planus only needs trance for 4 hours.

I was hoping one of the druids would suggest a camp site so that Planus could complain about stopping so soon.
