I disagree with you completely. She is absolutely facing reality, she's living reality. Whether or not she got the technical process right is irrelevant. I think it was pretty clear where the whole "judges order" thing and the "choice" her kid was given collided. Continually picking at her given the personal strain she was under worrying about her son's future was not in any way forcing her to deal with "reality."
Rev only got part of it right, he just posted information he knew and applied to a situation he knew
little about. He continually picked and picked at her even after she said she wasn't divulging any more info on the situation. CC backed up her story and I have personal, recent experience in similar situations. A waiver can be obtained to join the service even if you have a conviction. I can't recall the federal regulation that authorizes this, but the long and short of it is that even if you have a felony, the Army can review the case and request a waiver based upon the Secretary of Defense's current guidance for accepting waivers for enlistment.
In this case her son could have gotten a waiver approved and gotten a deferment that allowed him to enlist. It's extremely plausible. While he still has to tell them about everything (expunged, deferred, "sealed", or otherwise) technically the deferment helps the recruiter and him get a waiver to enlist.
Bottom line, according to the Army, you can in fact enlist with a felony conviction.
