It could be a very interesting and fun point if the matriach is from the Earthern plane. Kind of sad still for her.
Keen for more. She might bust in in Muon and think she is stealing her man.
Plot twist... Muon was the one setting Lin up for torture previously. She isnt now(or is she?) because she senses the origin energy in Lin.
It wouldn't be hard for her to direct Luna(crazy yandere) to act a certain way with Lin where Luna believes she's taking the best route to groom Lin.
