Tbh he made it bad keeping it a secret from dustin

I mean when he accepted the Dad's propositions with tutoring Dustin he could have just let Dustin in on it... Dustin would understand be like hey your dad said if I tutor you and watch over you he will give me a salary and internship offer... this will help with the expense for peach.... I mean there really aren't any disadvantages.. I mean Dustin needs to be tutored anyways and he's been worry about the money and his grades it's a win-win and the reports to the dad can just be what they both decide on... but hen he hid it from dustin that's betrayal.... accepting the deal doesnt matter its not like the father whats him to manipulate dustin
