Oh, my scenario was a deliberate mocking of the ending of ROBIN, where Steph betrays Tim's trust at Bruce's orders, and Tim is all "we can't be together fuck off rar you're not trustworthy" and then goes and breaks the epically untrustworthy Jason out of jail. But Dick resurrecting Terra because he can't trust Babs sort of automatically adds an implication of Dick/Terra to the act - if your first act after leaving your girlfriend is to do something huge for another girl, the natural subtext is "this is a romantic choice, a change in partners."
But if the Babs/Dick scenario is a reflection of the Steph/Tim scenario, then the Steph/Tim scenario is a reflection of the Babs/Dick one, and Jason becomes equivalent to Terra...
... look, I didn't say it was a particularly strong implication. But if you can't tie yourself in knots making things slashy on S_D of all places, where can you?
