He should've stayed dead for plot consistency. However, they should not have killed him off in the first place for a better plot line. A series of simple points woven together is best. But since we went down this path I need someone to explain why his parents were willing to kill one of their sons off casket and grave to keep them apart. It was over the top.

I love the two characters, but their relationship was formed via trauma bonding over one dead parent and one neglectful parent each, mixed with being lonely teenage boys. If I was a parent who was willing to admit my faults I would want them to get some time and space apart as well as some attention from me, and therapy. They could be gay or bi or whatever. That's none of my business. Just want to know they are both okay. In this case a year or two apart (not strictly they can visit one another and/or carry on an LDR) and some parental quality time. If they could get through that I would not care.

Instead, these parents just added more trauma by killing off one son and leaving the other to grieve. The story was so very random and made little sense. Just stop at the first one.
