It's difficult, but there must be a way.

Spoiler for EP 5:

Virgilia clearly stated in red that Natsuhi was not the culprit. Erika merely used red to say "no one but Natsuhi could kill everyone" but does that make it necessarily true, especially considering when we found out the 5 people had to have faked their deaths, because their bodies moved.

If Kyrie was Beatrice, then she would not abandon her family no matter what. (as said by Kasumi in EP4, she commented that mere disownment as punishment was too lenient at all if Kyrie had a bastard child with Rudolf. She insisted that there must be some secret deals behind.)

My wild speculation was that disownment was only a facade, marrying Rudolf was part of the plan to get the gold.

I'm sorry, but this is completely disregarding characterization. You're making Kyrie out to be some greedy gold digger.

As for abanding families - Kyrie probably considers Rudolf, Battler and Ange her family now (as Natsuhi thinks of the Ushiromiyas as her family) so she would never throw them away.
