One Day You Will Understand

In One Day You Will Understand, Alaric said that Hope couldn't have kids if she became a tribrid. However, Klaus was a hybrid as well and he was able to procreate with Hayley. Was this some sort of continuity error or will being a tribrid be different from being a hybrid?

I don't understand two things Cleo said to Alaric.

1) What did she mean by "My grandmother's precious granddaughters."? Is it means that her sisters told her about her grandmother's death or what? I don't understand why she mentioned her sisters in this conversation.

2) The second thing is her grandmother's afterlife. If she went to "heaven" aka Bright World aka Found Peace, why did Cleo said she watches over her as ancestor? After all, that would indicate that her village was practicing ancestral magic and had their own Ancestral Plane. But if that's true, and she is an ancestor in their village Ancestral Plane, she couldn't see Cleo in Mystic Falls like Davina (when she was in New Orleans Ancestral Plane) couldn't see Kol outside New Orleans. Unless by the ancestor she meant the Spirits (spirits of witches) at Peace, then it would make sense that her village was practicing spirit magic.

Cleo: My grandmother's precious granddaughters.

Cleo: She at least was safe from Malivore.

Cleo: Having ascended into the heavens.

Cleo: I believe she still watches over me as ancestor.

Cleo: It was her power running through my veins that helped me infuse the artifact I inspired Leonardo to create with magic that could shield me from Malivore.

After seeing Landon break Hope's heart in the latest episode, I think she might be better off ending things with Landon for good and getting a new love interest like Ethan. Do you agree or do you feel that Hope and Landon are endgame and are just going through a rough time? Though to be honest, things have been rough between them since Legacies first started airing.
