I had a horrible idea
So ployam STR marriage. Raven ran off after Yangs birth, supposedly didnt get a divorce. She gave Yang one get-out-of-trouble free card because shes her daughter
STR marriage, no divorce... Raven sees Ruby as 100% her daughter as much as Yang. She couldnt look at her at Haven because she looks so much like her dead wife. She was rude because Raven is rude in general
Essentially Raven not only has a portal to Ruby, but Ruby has one get-out-of-trouble free card
Which would be great in general but heres the horrible part of the idea. Raven saves Ruby and it pisses Yang off. Her mother can't be there for her but can show up for her reverse-step daughter? It wasnt even life threatening! She hung around to say goodbye afterwards! How could she do this to me?! Shes happy Ruby is okay but still.
Anyways that bitterness carries over till Yang sees Raven next which will be probably be years in the future and shes marinated in it. The cycle of upsetting each other continues
