Three endings are possible depending on how the player interacted with the Little Sisters, all narrated by Dr. Tenenbaum. 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.
