You know, as interesting a development as this is, I have to say this would be the most UNPLAUSIBLE thing going on in the Bat books, this break between Tim and Dick, because someone is missing.
No, not Bruce.
Alfred.
If ALFRED was there, Damian would shut up before ever letting a disrespectful snark out of his yap, Tim would have a good talking to about what is best and to learn to develop within the Bat family, and Dick would have a scowling admonishment. The ones that say so much with so little, and that hurt the most.
If ever the boys needed a father figure, it's now.
