I have my Evoker cousin kid who would have been hanging around the Wards since little because reasons. Also, Byrnes/Wards are tight like whoa ;) So Emma definitely knows him. He is a hellion.
Al I don't have anything for any of yours yet. But maybe in the future she could run into Grace and they could exchange blows or if the Heads need Al's services for some retconn missions? Either way, we shall come up with something!!
