>>714914035 (OP)In my opinion, the ending should go like this:
They realize the love of incest, despite being seriously wrong, would not outweigh the fact that they might die if they give up on each other (due to various factors). They embrace life and decide to have a family with each other even if somewhat dysfunctional (So, functional enough to survive perhaps.)
But enough about my fanfiction, it will be all to the cat author and her crazy ideas
