You have to put your own grief aside for a moment as you enter the Batcave, shutting your eyes to only hold back tears as the sound of fists hitting a punching bag and the pained cries of a distraught father are unmistakable.

Jason was gone.

Jason, the second Robin. Bruce's son. Your son.

Bruce and you had been married for a few years now, and these boys had been your children, Dick, then Jason.

And Jason's gone.

Thanks to the Joker.
