As Molly draws the circle, it becomes very apparent that standing still isn't exactly Strange's forte. He's not the sort of person who's good at stopping and staying still normally, never mind stopping and staying still when his mind feels like a thousand birds and the ground feels like rocks under his feet. He bounces in place, waiting impatiently until Molly finishes the spell and he feels the sensation of warmth.

He knows what to do. This magic is telling him to go. Strange gives Molly a thankful yet harried smile as he reaches over to grab her wrist and yank her behind him as he goes off in the direction of that fiend who cursed him.
