They did give an episode about them in Season 4, but I don't consider it as well done as Rarity and Sweetie Belle still and it's still relatively new so AJ and Applebloom had more moments to better bond and show it off.
"Sleepless in Ponyville" is generally lauded as the best Scootalove episode, and RD doesn't even care enough to notice Scootaloo is scared to death for the entire episode up until the very end. If that's the best they have to offer, I have to give it a big "nope."
