"Well then! You will not help me unless I let you free from the circle. I see no reason why you would help me if I freed you from the circle in the first place. You accept no alternative, so there's nothing either of us can do but wait until one of us changes their mind. And I have a feeling it won't be me."

This is bluster. As obvious from these conversations, Strange is not a patient sort of man. In a battle of stamina, it's obvious who's going to come out on top. Still, he's certainly haughty enough to think he'll outlast Solas in a battle of patience, as shown by the smug smile on his face.

Strange picks up a random book off the floor, stomps over to a chair in the hut, brushes off whatever papers or herbs were sitting on the chair and just sits down directly in it, directly in front of Solas, as he starts to flip through the book as if looking for a certain page. Passive aggressive reading is now a thing.
