AU to add to the list of AUs I'll never write: All of the Robins are de-aged to the age they were when they became Robin. Their memories are also reset to that point, and somehow they're in their Robin suits.

So you have a 16 year old Steph, desperately trying to wrangle 4 feral children who look nearly identical and won't tell her their names because "you do know what a secret identity is, don't you Stephanie?"
