Temporary deputy Eammon, guarding Nighthorse, arrests Henry trying to deliver something to Jacob's home, saying "I don't know you." In previous season's episodes, while Eammon was on loan from the Cumberland County Sheriff's Dept. he interacted in the Red Pony, which Henry managed. It would be impossible for Eammon to spend anytime with Walt and the two deputies without knowing Henry Standingbear.
At the 42:08 mark, when Walt is yelling at Jacob, Robert Taylor accidentally switches to his native Australian accent when Walt says "You wanted to get me out of the way, so you could resume (the accent is very clear here) your profitable arrangement....." The word 'resume' is clearly accented.
