I wish for a happy ending

Since obviously this will entirely ended up with an unexpected baby, a daughter even, which of course will be a whole new round of accusations and misunderstandings, but! But. I sure wish that doctor won't ever preach that stupid incestuous family tradition upon the two babies. I want Damien and future baby sister to grow up happily as a very kind and happy child with her kind (and overly overprotective) older brother. I don't read the novel but I wish it will come true.
