I dunno, I'm for the Babs side of Babs/Dinah, but I see it the same way I see Bruce/Clark, as possibly (but never definitely!) unrequited. It would really help if Dinah and Ollie's marriage weren't being written as such a wallbanger that they'd be as likely to split as Lois and Clark, so we could put the anger about them being together behind us and get back to feeling sorry for Babs.
