My favorite part of that Showcase chapter is the part where Dinah, unthinking, gives away that she's got a Bat on her shoulder, and Lois instantly picks up on it, but amiably lets it slide once Dinah tells her she can't tell her. I like to think Lois connected the dots and remembered Babs helping save her life and free the kids here a hundred-odd issues later when Kat tried to sic her on Oracle.
