Boyd does answer to her. If the LA staff are surprised when they find out that Boyd is the 'big bad' then they will be incredibly surprised wheh they discover that he was only a front man for the real power in charge. I mean, she has access to all of Adelle's files (she inventories them), sets up the appointments (thus allowing anyone she deems fit to have access to Adelle) and no one would ever suspect the administrative assistant. The perfect cover. She will orchestrate everything from behind the scenes. Her time will come.

A very Joss like twist.
