Happy trails.

I guess Moss is waving his lasso at the horse to get it moving, but it still looks like he's playing a game of giant, live-action ring toss.  The horse looks sad to be leaving.  She really wanted to help, but got injured along the way through no fault of her own.  Poor thing will probably be reminded of that fact every time the story is told.

Don't be afraid for Faline and her doe friend.  They're in no danger.  The animals of the forest have put aside their differences (and predator-prey tendencies) in order to get rid of Kelly (and to a lesser extent, Brawny).  The deer are just there to distract their quarry while the bobcat, cougar, mountain lion, whatever, sneaks up from behind.  Of course, if I were those deer, I'd make sure that I was out of sight when Kelly and Brawny are finally dealt with.  Sure, the allegiances will hold during the plan, but once it's been carried out, there's no telling how soon things will go back to normal.
