Pietro looked confused by this reaction. As far as he knew, the Avengers had sent Clint and Wanda, and knew very well what the plan had been. It took a moment for realization to break over his face.
"...They weren't supposed to come. I- nn- I don't know. I don't know who's dead. They were shooting people, and Wanda said our father- she said he destroyed it. That people had died. And then she blew it up. Just like that." And while Pietro knew his father likely wasn't there, he had no way of knowing whether it had been occupied by any one else, or how the injured people in the cells had fared following the explosion. "...I thought you knew."
