Things with my daughter are guardedly better.
First off, she requested and got an immediate transfer to a new room. Things were getting toxic with her roommate -- not hate-and-vitriol toxic, but 'getting snarky texts' toxic. She actually wasn't sure she wanted to move, but when the roommate sent a text asking, snarkily, why didn't you tell me that you are moving to a different room - which hadn't been yet decided (though it was mentioned), she decided I have to get out of here. Which happened that very night. She is now in a room with the fourth roommate -- the one who informed on them. They are both happy. The change in my daughter's voice was amazing.
Second, I asked for opinions from the mother of one of the other cadets -- but not just any mother of any cadet; this one had been the administrator of the Facebook page for parents of kids in the cadet group, and her son had been the highest-ranking cadet in the corps before he graduated. I figured if anyone would understand, yet hold up the corps of cadets viewpoint, she would. She told me that yes, it was serious, but she doubted any lasting damage would be done to my daughter -- which means, nothing that will keep her from graduating with the corps. (She told me that she knew of one cadet, last year, who decided to bring alcohol into the dorm, and was informed two days before graduation that he would not be graduating with the corps of cadets - with his class, yes, but with the corps, no - which meant he would not be getting a commission, which meant he would not be going into the military. Enjoy your life, kid. My daughter did not bring in or use alcohol, but the others involved in this fandango did.)
Third, another cadet was talking to a member of the corps staff who happens to know my daughter fairly well. The staff member made an offhand remark that there would be repercussions for my daughter, but he doubted that they would be serious. The cadet happens to be friends with my daughter's boyfriend, so the word was passed pretty quickly.
Of course, it ain't over till it's over.... but things aren't quite as gloomy as they were two days ago.
