Looking for specific Avengers/Harry Potter crossover
I read it fairly recently and I think it was a one-shot or two-shot. It started with Harry storming the Helicarrier, seemingly evil and threatening, demanding Fury to return what he's stolen from him. The Avengers were there and Steve was very judgmental and said something about "guys like you". Then it was revealed that Fury had kidnapped Teddy, who was ill due to missing his potions, and Harry was just a parent defending his child.
Anyone?
