Best part is how, not only does she call Babs out while she's on stalker duty, but after Dinah clubs her senseless, drags her back to the Tower, breaks in and literally drops her at Barbara's feet, her response is not "holy shit this woman Babs wanted me to keep an eye on is violent and powerful and right in the middle of our home base, gotta contain her," it's "I'll just let you two catch up. Toodles!" HEE.
