I think the best possible outcome of curent state of plot would be Heil and River being together plus River helping Khaol in some way so that he would move forward. Everyone would be happy. (=・ω・=)
I' m happy and są that it is going to the end. I hope they will have good life at last
Sad* gosh ┑(￣Д ￣)┍
