Forgive me if this has been touched on before, but did the creators actually confirm with 100% certainty that Shayera was the mother of Warhawk? There's no question John was the father, but the father-son conversation in "The Once And Future Thing, Part II: Time, Warped" went exactly like this:
Warhawk: "This is a little weird for everybody. I'm Warhawk. Rex Stewart."
John: "Your mother...who is she?"
Warhawk: "Kind of obvious, don't you think?"
Batman (Bruce): "Even if it isn't, leave it be. You don't want to know too much about your future."
Batman (Terry): "Trust me, you really don't."
Static: "Shayera was one cranky pregnant lady. Although to be fair, If I'd laid an egg that size..."
Warhawk: "He's kidding, Dad. Not that I understand why you think this is anything to joke about."
Static was the only one who came right out and said it was Shayera, but at least part of his statement was him joking, which prompted Warhawk to call him out on it. John was dating at least one other woman with animal-powers that we know of (Vixen), who could have just as easily been responsible for Warhawk's wings and powers, I suppose. Do we know for a fact that Shayera was Warhawk's mother? Has this been confirmed?
