Few things get the Atlantis gang as excited as the floating remains of an entire Wraith fleet. Indeed, the debris that Sheppard's puddle-jumper flies through is nearly as thick as the rings of Saturn. Why? 'Cause the Ancients developed their own version of the Manhattan Project a super-duper doomsday weapon that McKay (whose ego is roughly the size of Manhattan) believes he can reactivate. How powerful is it? "It makes zero-point modules seem like alkaline batteries in comparison," insists our mad scientist. I don't know what that means myself, but it impressed Weir enough to give him the go-ahead. So did it blow up in his face? Is Hilary Duff ubiquitous? If McKay did master this technology, it would mean the end of the series, because the Wraith would no longer be a threat. So it was only a matter of time before the hot air drained from McKay's hubris. "I promise not to be right all the time," he vowed to Sheppard after inadvertently destroying the planet. Cheer up, Rod; I'm sure you'll be back to your old pompous self in no time. Another dead-world survivor, Ronon, nearly destroyed his friendship with Teyla after asking her to arrange a meeting with his old military commander and then coldly gunning the man down like he was Old Yeller with rabies. Although Teyla sympathized with Ronon's fury toward Kell who sent thousands of Ronon's comrades to their death so he could escape the Wraith she read him the riot act because a) their Earth allies frown on summary executions and b) she hates being used by muscular, hungover dudes with dreads.
