Thing with Babs is that she does have a pretty decent emotional IQ but it mostly applies to other people. She can often figure out what's going on with folks, and she almost always knows how to push buttons, but she's kind of a dope when it's her own behavior in question (something she shares, or at least should share, with Bruce). Plus, judging from her romantic history, she's not on real good terms with the girl-lovin' part of her sexuality, and she can't be much more than nineteen or twenty in that scene with Helena, so being clumsy as hell in testing those waters is sort of to be expected.
