You & I, Defending

Oneshot. Part of E're Series but can be read alone. If there was one thing the Avengers knew, it was that you didn't mess with the Starks. But it seems that the criminal world hasn't learned that lesson yet; and when the Avengers are out of the Tower, the rest of the household must teach that very important lesson. (Hp not a really a factor, set in late chapters of Awakening.)
