I created mine to support the other one whenever I ask something to do something and vice versa and they should decide on who should do it best and if I ask ESS something, Fae should do it and vice versa…lol… etc etc…
That way I don’t have to remember who does what best, and when and blah, blah, blah, etc…like you’re worried about above…
I call them “the twins” because of this but I sense one of them doesn’t like that much 
(when you’re servitor has an ego …sigh… 
)
