RO's reactions towards an overworked/workaholic MC who treats their job as a way to escape their truma?
Loreena: She would be worried, but she knows what trauma can do to a person. She wouldn't intervene unless it got too bad. (Like not sleeping or eating for days on end.) She would just try to be there as much as she could. Offering up distractions if it meant you would feel better.
Robin/Robyn: R would try to make you laugh and do everything they could to pull you away from your work. They know that your work is important to you, but that doesn't mean you get to shrug of basic necessities to your survival in favor of it.
Edmund: Edmund would be tense the entire time. Staring at you with an impassive gaze before glancing at the clock. That would happen for a couple moments, before he would sigh and take you to bed. He wasn't going to have a sleep deprived Dracaryean on his hands. (Nor an unhealthy one.)
Esmé: Esmé is the queen of being a workaholic. For a long time her work was all she had, barring a few close friends, so Esmé would know exactly what to do. (After all she sometimes works 20 hour days... her personal record is two weeks.) She woud simply take you in her arms and do anything that you asked, within reason and if it didn't involve work of any kind, she knows that your brain needed to do something. Anything to keep it busy so you didn't remember. And she would be an excellent distraction.
Ayleth: Ayleth probably wouldn't notice it much at first. Not that she wouldn't notice something was wrong with you, but she just is oblivious to that sort of thing sometimes. However, when she does notice she would do everything in her power to curb that hobby. Trying to talk to you about your problems, because what you were doing wasn't healthy. How you were coping wasn't healthy, and she would want to do anything she could to help.
Cedric: Cedric would notice right away because he has been with you for so long. He would try to do everything that worked when you were both children. Any distraction is a good distraction, as long as death wasn't involved, and he would be more than sure to keep it that way.
Caspian: Caspian is well aware of the coping mechanism in place. It was one of things he probably pegged you for the moment he saw you. Knowing this he would have ample time to prepare for it. Making sure that any signs would be dealt with, because he has seen what a habit like that can do to a person. And he won't let it happen to you.
Aghadi: Aghadi would try and be gentle about it. Making sure that you still had everything to eat and drink while you were working. Bringing it to you in manageable pieces, because he knows you won't eat it if it means that too much time would be spent chewing. However, if it went on for too long he would take you away from you work. Wanting to let you destress in a different environment.
Phenir: Phenir would feel saddened that this was happening, but he wouldn't be underprepared for it. He would do his best in helping you, but he's never been that good with understanding things. (Mostly because he gets so flustered.) He would make sure that you had everything you could ever ask for and more.
Revian: Revian wouldn't put up with it. She would not be one to coddle such behavior. She understands that work is important but taking it the degree you have is too far. She would never be one to say that such a bad habit was good. She wouldn't stand to side and let you wither away. She wouldn't let your mind take control and shut down like it has done. She would fight for you with everything that she was.
