(McKay and the Wraith "Todd" are holding back while Sheppard and Ronon clear the way)
McKay: There's on thing I don't understand - back when you defeated the Ancients, how'd you get your hands on the ZPM?
Todd: The Lanteans were powerful but careless. Believing their ship's were unbeatable, they sent them deeper and deeper in Wraith controlled territory, trying to weed us out. It took month's but eventually we were able to capture three of them; each one, powered by a ZPM.
McKay: At which point, you brought them back here.
Todd: Within weeks, our army had grown to hundreds of times its original size. From that point on, the tide of war turned in our favor and there was nothing the Lanteans could do.
Sheppard: Save the history lesson for later, let's go.
