If Baked Alaska happened, how would Ruby react?

Okay, I know Baked Alaska (NeoxYang) is just a fanart and fanfiction ship that no one ever expected to actually happen in the show. It won't. But, if it did happen in a fanfiction or something, how do you think Ruby would react if she found out? How would Ruby react to her sister being with the girl that hates Ruby and has tried to kill her and did actually get her to basically commit suicide in the Ever After?
