Killian’s band is to the right (some stationary, some already moving away), and another band is to the left. Killian stands protectively between them. The chase through the trees has already happened, and the other band is drinking at a seep. Killian, here, seems calm and only observant. What thoughts does he have?

Hopefully he’s thinking life is goo, everyone is safe and there is water to be had. And we have TJ looking out for us !
I love that the horses are always aware!
He does look as though he’s thinking all is good and right in his world!
