   Summary

   I killed him.

   It repeats in his mind over and over again as he stares down at the bloody, gory mess that used to be Angstrom.

   But the sound of blood rapidly rushing to his ears begins to quiet, and it’s then that he hears the heartbreaking wails of a baby.

   "Oliver?!"

    

   Or: Mark and Oliver get trapped in Gotham. And with Angstrom dead, getting back to their universe has gotten a whole lot harder.
