So based on the clues we are lead to think...the dumb father picked up a troublesome (delusional) pregnant maid, then this maid hoping for love that she didn't receive, out of jealousy killed the main wife seeing as the maid had that suspicious letter and an herbalist at that, took the duties acting as the wife, on top of that bringing up a blonde child whose condition to "love" is to love another person's lover (which sounds oh so very similar btw like mother like daughter) or the blonde is the only one really delusional here
