Big picture, nothing will happen. They never do, not there, wayyy too much brass involved for anything to change. My junior year a girl who was successfully found guilty of an honor violation (it was her second violation and second time with a guilty verdict) was recommended for dis-enrollment, which in 99.99% of cases means you're gone...unless your daddy is a general. So this chicks dad is a general, forgot the number of stars, and she was personally retained by the commandant of cadets, a former KCVS Wing/CC, who decided to reverse the boards decision.
I will say this kids story sounds ed up, mostly OSI's handling of things, however, it usually takes a lot more than sneaking off campus to get kicked out. However, I'm sure there is more info about his circumstances the former cadet didn't offer up in this story
