I felt the austere tone of the piece was a great metaphor for the life he needs to lead to do this show. I believe he takes this opportunity very seriously and is old school about the discipline. It doesn't mention if he is an extrovert or an introvert, but I am guessing an introvert. He feels he has a lot to prove with this show-it rides on him, he comes from privilege and wants to prove himself as committed. If he is an introvert he won't show many colors during an interview or may be more reserved, so the writer needs to produce some tension.
Many actors I've met (Marin Mazzie, Ute Lemper, Jackie Burns) have discussed a similar approach when they have a lead role in a demanding show. I don't think he is out of the realm of doing what is required, it just seems weirder because he is so young and we expect younger performers to be more resilient.
Also, much like N2N, this is a show with that very emotionally invested (ie obsessive) fan base that can wear on you. I think that emotional toll is harder. People wanting to share stories, etc. That will give the kid anxiety and stress. They should always take him out a back alley to be honest. I think he's too young for the stage door crowd on this one. Especially if he is introverted.
I have great respect for him and his desire to make all of his shows. That is how it should be when you are carrying a show. It's how Chita, Patti, Bernadette, Audra, etc. all roll.
