I want to read a fic where all the Robins are rejuvenated to the age where they became Robin in the first place, but they remember everything, like, only their bodies are rejuvenated, not their minds.
Tim and Jason meet up right away, then they find Damian (who's the one who's changed the least, obviously), Stephanie quickly arrives with them and they try to figure out what happened while they search for Dick, since he disappeared.
It's not until a while later that they manage to find him, and he already has the wizard who rejuvenated them tied up and unconscious, and the scene is just... Something else.
Everyone knows that Dick was clearly the youngest of them when he became Robin, he was barely 9 years old... But they had no idea how SMALL he really was, not even Tim, who even though he saw him as Robin, Dick always seemed bigger than him being older, not like now, when Tim is in his body a few years older than Dick was when he became Robin... Well, when Robin became a vigilante, rather.
And Dick obviously continues to act like his usual self, he's a leader who quickly takes control of the situation and starts organizing them... But it's just weird for everyone, because, okay, they're all little now... But even for them, Dick is much smaller and it's just... As surprising as it is distressing.
