Okay, think along with me if you like 
I was just watching my boyfriend siding with the templars and there is a part where the Envy demon dressed up as Leliana says "Is this shape useful? Will it let me know you? Everything tells me about you, so will this: Watch"
Something about the way she says "Everything" keeps bugging me, if "everything" is being used as "anything" then there is no reason to say "so will this" because "everything" would already cover that, right?
Similar to Cole's post breakup banter where he says " He hurts, an old pain from before, when everything sang the same. You're real and it means everyone could be real. It changes everything but it can't" I also find it peculair that focus in that first sentence lies on "could" instead of "everyone"
In Awakening when you spoke to the Architect ( who is probably one of the Magisters as well with his talkative nature and all
) and the Mother, they describe the call from the Old Gods as music. And then there are the Dwarves who claim that they find lyrium by listening to the Stone sing. Also lyrium apparently sings as well according to Justice and Cole ( in Asunder).. And then there was a lot of people singing on the way towards Skyhold
...
No but seriously, what is this Everything?
