I'm a bit curious about Dick Grayson's training prior to becoming Robin. I'm not sure if you're ever planning to do an "origin" type episode for him, so I understand if you can't answer some of these questions due to spoilers. I've also looked through the archive, and I didn't see these questions asked, but if they were I appologies.

1. How long after adopting Dick, did Bruce wait before revealing his identity as Batman? Or did Dick find it out for himself?
2. How long did Bruce train Dick before allowing him to become Robin.
3. Who came up with using a Robin for Dick's hero identity in this continuity? Bruce or Dick or Dick's parents? (In some continuities the Grayson's nicknamed Dick "robin" due to him being born on the first of spring).
4. In the original Young Justice comic, the team were rather resentful towards Robin (Tim Drake) for keeping his identity secret from them, under Batman's orders. Does the animated Young Justice team (with the obvious exception of Wally) feel the same way towards Robin (Dick Grayson)?
