Or convince Sarah that Dan doesn't trust her because he's setting up cameras everywhere and not telling her he's doing it. I just picture Lester changing the locks that Dan changed, after that argument, and Sarah just watches him do it...who knows, maybe it turns her on.
It would be great to give everyone what they want.
Lester to install cameras and give Dan access to them so that he can satisfy his voyeuristic desires, but until he and Sarah create a full-fledged family. Lester to move in with Sarah to create a happy family. The only thing is that Sarah must influence Lester regarding hygiene and pay attention to healthy eating and the gym. The children will be happy to have such a caring father as Lester who will always be there and can open up the wonderful world of computer games to them, unlike Dan, whose love for children consists only in the words "I miss the twins and that's all". This will be the same happy ending of the story that DS promised. I love happy endings of stories when each character gets what he wants.
Dan is a weak-willed loser who has repeatedly described DS, he will not be able to give his children a normal upbringing, which Sarah understands on a subconscious level as a mother. As a woman who loves her children, which is also described a lot by the author, the obvious choice is Lester, who will be able to provide security, care, and, most importantly, financial stability, and it doesn't matter what methods he uses, the main result is. The question of love here is worthless because this is America, in which love has been replaced by the meaning "Nothing personal, it's just business", that is, money in this country will always take priority over love.
