I've been wanting to change my ID for a while, but I couldn't think of what to change it to until just this morning
I can imagine the scenario behind this being that Dick is playing a game of "Catch the Robin" that Damian isn't too enthusiastic about (but secretly is enjoying somewhere in that adorable psychotic mind of his).
Either that or Damian is falling randomly from the sky (as Robins often do) and Dick looks up and realizes that he's getting his baby bird back (just like he asked for in his letter to Santa!).
Either way I think the reunion will be a happy one (for Dick anyway).
