They aren't, she's in love with Alex in this universe...for now, and Batwoman might not exist. Different continuity, different romance.

M'gann sees J'onn as an uncle on Prime Earth, here she's in love with him and will have mint-colored martian babies hopefully. Also I'm super cool with it, because friggin' DAMN is J'onn alone across the board, he deserves someone nice.
