Sometimes bodies are not recovered, claimed by the Seas, lost and never to be let go in order to reclaim; it gave back Shad's body.
In the Dark Knight, Joker said, "In their last moments, people show you who they really are..."
I feel, spiritually, it gave back Shad because of his final moments in terms of show his inner character by telling the guards to save his son first; he would rather die, then to see his son die.
