Okay, Alex was sure he was going to be sick. But it took every ounce of willpower he had not to vomit at the sight and sound of Dr. McCoy and Josh popping the arm back into place. He did look away though, because seriously? Who wanted to watch that. Alex looked anywhere but at Josh for a few minutes while he healed. Alex should just be incredibly lucky that he had a roommate whose powers were of the beneficial mending type.
Blinking away all that pent up fear he had only minutes ago about Josh dying, Alex was back to being apologetic. He crouched down next to Josh, looking a mixture of concern, apprehensive.. and trying really hard not to smile. It wasn't appropriate but Josh was okay, he wanted to! "How are you feeling..?" He asked, looking afraid if that was the wrong question -- though it was pretty dumb.
Alex just blasted him into a wall -- how would he be feeling if the roles were reversed?
