Surprising enemy arrives in Atlantis

New details received by GateWorld on the upcoming Stargate Atlantis episode “Critical Mass” reveal the arrival of a surprising enemy in the Ancient city. Beware of spoilers in the report below!

As previously reported, the Atlantis team scrambles to protect the lost city of the Ancients once again when someone among them apparently alerts the Wraith to their presence (story). Wraith ships are on the way, and some suspect that a scientist who has just arrived from Earth, Dr. Allison Seagle, may be the culprit.

But the enemy within is no mere Wraith sympathizer: A Goa’uld has infiltrated the base. In addition to the Wraith ships now en route, a bomb has been set to detonate, forcing Sheppard and his team to race against the clock and determine who is human and who is under Goa’uld control.

Written by Carl Binder and directed by Andy Mikita, “Critical Mass” will go before cameras in late July for a winter 2006 premiere on The SCI FI Channel. Visit GateWorld’s episode guide to learn more!
