A great learning opportunity.
Language is hard for Ethan, so tutor will need the ability to use humor and/or be tough as situationally required to facilitate learning. A playful attitude but a get down to business realism will work best.
expect a lot from him but are flexible to progress to there;
have something else to work on with him (music, drama, reading, etc.) so conversation is a tool in working together;
they first build his trust, then they intersperse pressure/work on his weaknesses while applauding what he accomplishes.
