I have an idea. One of the main reasons Remor, dad left him and his mom is because he was gay. And after he reunites with his son Remor he expresses that by introducing his boyfriend/husband to him along with apologizing to Remor and his mother for leaving them and in turn Remor had to come to terms with his dad's sudden reappearance and the fact that he now wants to have a relationship with his grandkids and great-grandkids.
