Even in a Dick/Babs post my biggest squee goes for Dick and Tim trainsurfing.
I do not understand why anybody would want to retcon Dick/Babs' original relationship to each other. And Babs really is cute here. I rooted for this pairing then, but I feel like it wound up being a not good relationship for the two of them. But in a way that was organic and surprising for the characters, so it makes it interesting, if that makes sense. Like it wasn't just random drama thrown in to separate them, it was a real situation where you (or at least I) could see they weren't good for each other.
