I’ve just finished this episode, and agree with your questions. In one scene you could see a school photo of a young boy, I presume that was one of the sister’s children, and made me wonder if they had had the opportunity to take stuff that was their mums that they wanted. She obviously had a whole house and three teenage children when she died so would have had furniture, clothes, books, a whole house of things. And the couple tonight were married with no children when they moved in so whose stuff was it, and if it was all theirs what had happened to the sisters things, her bed, her dining table, her saucepans, her pictures? I wish they had addressed this even slightly.
