Chris should be truly admired for standing up for his principles in not wanting to be involved in a venture that serves alcohol due to his deceased father-in-law. Good lesson here in values.
And Will is so mature too with high values/principles and is proud of his Dad for not selling out on his values unlike most kids who would've only been thinking about baseball camp or whatever else they wanted.
At the end when everything was finally explained Will goes and tells his Dad he was glad he was his Dad. If I was in this family I'd be telling Will I was glad he was my brother, because he's my idea of "the perfect brother." ( very nice, mature, polite, smart, fun, good moral values, etc. )
