Tracker

The team comes to the aid of a village under Wraith threat, but Ronon and McKay must rescue one of their own when Dr. Keller is kidnapped by another Runner, like Ronon, named Kiryk, who has brought Wraith hunters to the planet. Ronon is forced to act as a Runner so he can save Dr. Keller from Kiryk. It is eventually revealed that Keller was kidnapped because he needed her help to treat an injured little girl traveling with him and he only kidnapped her out of desperation as he couldn't risk her refusing to help. Keller treats the girl and having earned Kiryk's trust, disables his tracking device so he can be free like Ronon before they hook up with Ronon and McKay. The group defeats a Wraith attack, but find the Stargate guarded by a group of Wraith and two Darts. Kiryk lures the Wraith through the Stargate to another planet and his fate is unknown, but his sacrifice allows the group to return to Atlantis where the little girl recovers and is adopted by a family on the planet where Keller was kidnapped as her own planet was destroyed.
