I really wish that the whole Steph-Robin thing had lasted a bit longer. I mean, I can see why it wasn't meant to be, but when Bats isn't acting like a jerk towards her, their relationship actually works very well. After all, the whole reason that Robin was brought into the formula was to provide a lighthearted foil for Batman's grimness - and Steph is just such a smartass, makin' with the quips whenever she can. I think if they had actually allowed this to stick around for a few issues more, we could've gotten some satisfying stuff out of it.
