S2, E11: Captured by the Wraith Sheppard (Joe Flanigan) Teyla (Rachel Luttrell) Ronon (Jason Momoa) and Ford (Rainbow Sun Francks) are being held hostage aboard a hive ship. As the team desperately searches for some means of escape they are shocked to discover a coalition of Wraith followers on board the ship. McKay who is still stranded on Ford's planet soon realizes that the team has been captured. In order to escape the planet he comes up with an unconventional plan: he injects himself with a massive amount of the dangerous Wraith enzyme. The drug provides him with brute strength and after knocking the guards that surround him unconscious he is able to dial the gate and leave the planet. When he arrives on Atlantis completely incoherent Dr. Weir (Torri Higginson) and Dr. Beckett (Paul McGillion) put him under immediate medical supervision. Once recovered McKay is able to calculate the location of the ship upon which the team is stranded. As tensions rise on the hive ship between the Wraith and the Atlantis team he and Caldwell (Mitch Pileggi) must devise a plan to bring the rest of their team to safety.
