Season 3's "Sunday" reveals that Teyla has a romantic interest in an unnamed male, who is presumably unaware of her feelings. In season 4, however, Teyla discovers that she is pregnant at the end of "Missing". The child's father is an Athosian named Kanaan. When Teyla is three months pregnant in "Be All My Sins Remember'd", Sheppard suspends her from active duty. In the meantime, the Athosian people have gone missing, and the search for clues to their disappearance proves a season-long arc for Teyla. Michael and his genetic experiments to create Wraith/Human Hybrids are found out to be responsible for the Athosian's disappearance near the end of season 4. At the beginning of season 5, Teyla gives birth to a son, whom she names Torren John after her father and Sheppard. (When fans pointed out that Teyla had introduced herself as "daughter of Tagan" in "Rising", implying her father's name as Tagan, executive producer Joseph Mallozzi suggested that Teyla may have been referring to her mother.)
