Mighty Avengers #21 (2007)

Stature and Vision arrive at the ruins of Avengers Mansion to answer a call from Wiccan about magic Billy has detected that could pose a global threat. They are stunned to find the other members of the Young Avengers turned to stone, victims of an effect that is quickly spreading. As Vision scoops Cassie up and flies towards safety, their shock is compounded by the sudden appearance of the Scarlet Witch in the air in front of them. In a flash of red light, all three of them disappear.
