its andrew babe
i know it sounds REALLY stupid on the surface, and thats kind of what makes me think marlene will do it.
Andrews weird 'im trying to save the girls, oh wait im adopted!' plot sounds like it fits perfectly in with whats been going on. he was CeCe's brother, and was trying to STOP CeCe from going too far with the dollhouse. and now that CeCe is dead he wants revenge.
its the most boring answer i can think of but considering how odd his use in 6A was it sounds like marlene might have been setting him up for it since they seemed to know what their 5 years forward plan was at that time.
i feel like a troll just typing this, but this is what hellish life is like in a post-shower world.
