Based on the title I have some doubts about his not be the actor plan
I expect he'll try to quit once their money problems are sorted out, only for mom to confront him on whether he genuinely wants to act, and how she'll support him if he does. He refuses, but uhh maybe realizes that his mom wants him to be happy, in realizing his dream, they hug it out, bla2. Either way I'm just here for him bonding with mom, so any narrative paths work.
