So, lately I heard a very interesting theory about Swain, suggesting that not he, but Beatrice is the actual master.

So Beatrice kinda controls him and casts his spells for hhim, and in his ult even takes his form.
Also, when Swain dies, Beatrice flies back to the fountain to retain control over Swain before he can escape. And in the lore he didn't want mgical treatment because maybe it could've killed the connection between them.

I, myself, think that it makes sense, but everything does when you think about it, so what do you say?
