“Broken Ties” is episode three of season five of Stargate: Atlantis.
Previously, in “Reunion”, Ronon met three fellow Satedan survivors. They turned out to be Wraith worshippers and two of them died in the process of betraying him. The third, Tyre, escaped, and captures Ronon in order to turn him over to the Wraith. Tyre is suffering withdrawal symptoms as the Wraith have ceased supplying him with stolen life, and believes that by surrendering Ronon to the Wraith that they will start giving him life again.
The team must find Ronon before his Wraith captor can succeed in turning him the same way Tyre was turned. It doesn’t look like they have succeeded.
Meanwhile, Teyla is uncertain about returning to the team after the birth of her son.
