James watched as Luke practiced against the dummy, taking in his form and movement with silent admiration and perhaps sizing him up a bit, disappointed when his presence was noticed and the man stopped. "Yep," he blinked a few times, not sure why he was suddenly so distracted. He hadn't seen many other men shirtless, and the tattoos were definitely something new. He was determined to keep his own shirt on, not quite comfortable with the missing limb and the extensive scarring around his shoulder where the prosthetic used to attach and the metal plating remained. He rubbed at it absently, remembering the offer he still wasn't comfortable with taking. Not until he got a chance to know the other and his intentions first.
"Never one to back down from a challenge," he grinned. Or so he'd been told, and it was easy enough to believe. He started a few warm-up stretches of his own, glad he'd finally get a chance to give his muscles a proper work out instead of carrying books around all day.
