Now that Damian is back, has he asked Bruce or another bat-family member about where Dick is/ how he died? If so, what was his reaction?

Dicks death was terribly handled in regards to bat family reactions and there's no reason for batman to hide it from the bat family. But no damian doesn't seem to notice Dicks absence. Damian gives no f*cks.

I heard that the reunion between Dick and Damian is going to be tackled in a future issue whether that's Batman and Robin or Grayson I'm not sure. Damian's relationship with Dick is pretty important their not going to skate over that.
