Where did you all Go?

Tommy lived a decent life, a dad that was both strict and loving, two older brothers that always looked out for him and teased him, and a younger brother that followed him everywhere. Everything was going great, until Philza decided he wanted a daughter too. One thing led to another, and soon enough the life Tommy once knew doesn't seem to be there. Life at home was changing too, he was being replaced, would anyone notice if Tommy even left now?
