Lina is rude, childish, stupid and irritating, but there's a reason, I'm not touching her head, I don't like her. But there is a reason why she is like this and it is very sad. I read the novel. And I really love Tupan. And Rouche, haaaaa best husband, Seria is the best.
No, the child does not belong to the high priest, nor to any other character who appeared in the story.
