If the player has rescued all the Little Sisters , five of them return to the surface with Jack and go on to live full lives under his care , eventually surrounding him on his death bed .
If the player harvested no Little Sisters ( thereby saving their lives ) , the ending shows five Little Sisters returning to the surface with Jack and living full lives under his care , including their graduating from college , getting married , and having children ; it ends on a heart-warming tone , with an elderly Jack surrounded on his deathbed by all five of the adult Little Sisters .
