Watching her ride around, and seeing how happy she seemed gave Jack a basic little thrill, innocent intentions (and love for Ennis) be damned. Seeing a pretty lady bounce up and down on his horse struck a chord somewhere in him, and he couldn't help but find himself thinking of her in an entirely less-than-innocent manner. He tried to shake it off, needing to find something to do, to distract himself.
He let her go around a few more times, before waving her over. "Seems a shame t'keep ya in this dusty ring all day. Y'wanna gimme a sec to saddle up, an' I'll show ya 'round?"
