Ok I got an theory,Remmber my theory about the runes?

If not,Let me remind you,Each rune have a specific part of a code/Ritual on it,That the protagonist have to learn or memorize,And then whenever he got enough parts of those codes he can buy for himself an ability or upgrade one,So far so good,(Explains the muttering from when you use the abilities and etc.)

Now I think,That what Delilah did to Corvo at the start of the Dishonored 2,Is basicly making him forget/Lock his abilities,Simple,Whenever you accpet the mark from the Outsider,Corvo say's:"The void...It've alway be there" now this shows us that,Delilah never stole Corvo's mark,Only locked it somehow or making Corvo forget the parts of the code.

So in my opinion,The Outsider can't acutaly take what he gave,Only lock it or steal it for a time,Since every soul in Dishonored has a connection to the void,But the Outsider unlocks it,Somehow again,We can base that on many books,Above that,In real life,Some theories say that our souls alway have spiritual connection,But higher souls lock it or we choose to lock it,I know it's an heavy theory,But assuming it's right,This can be groundbreaking,Meaning that the Outsider is just a tool for the void and the void has it's own "Mind" or "Concussion"
