New details have arrived at GateWorld for “Broken Ties,” the third episode of Stargate Atlantis‘s upcoming fifth season! The episode will center on Ronon Dex, who is once again reunited with an old friend.

The episode will guest star actor Mark Dacascos, who reprises his role of the former Satedan soldier Tyre. One year earlier Ronon was reunited with Tyre and two other Satedan friends, who he had believed perished in the Wraith attack on their homeworld (“Reunion”).

The Satedans led Ronon and the Atlantis team on a dangerous mission into a Wraith laboratory, only to betray them. Tyre and his friends had been tortured by the Wraith and forcibly converted into Wraith worshipers — humans who willingly serve the Wraith as their lords and masters.

In “Broken Ties,” Ronon is reunited with Tyre once again. Apparently having turned on his new masters and broken free of their brainwashing, Tyre hopes to rebuild the relationship with Ronon and Atlantis that has been destroyed.

But when Ronon is captured by the Wraith, Colonel Sheppard and the team face a startling new problem: Could the Wraith manage to turn Ronon into a Wraith worshiper, like they did to his friends? How could they fight a friend, someone they consider to be one of their own? A confident Wraith takes on the challenge, bringing Ronon to the edge of death and boasting of the Wraith’s power and their victories over powerful foes, such as the Ancients.

The episode will also see a dramatic change in Ronon’s appearance: the loss of his signature dreadlocks, which Ronon himself cuts in the course of his experience with the Wraith torturer. Actor Jason Momoa actually cut off the heavy dreadlocks during the show’s hiatus, and is having them painstakingly reattached for purposes of continuity in the first three episodes of the season.

“Broken Ties” is expected to go before cameras in early March, and will air later this year on SCI FI Channel. Visit GateWorld’s Season Five episode guide to learn more about the new season!
