After the space battle at the home of the Replicators, Rodney got a signal from our favorite Wraith, Todd. :)
They tracked down the signal, and found a hiveship, with no living wraith on it. They also find the previous destination of the ship. Its a cloning facility. 1000s of wraith are made on that labour. After John, Ronon and Rodney freed Todd, and with Teylas help they defeated the hive Queen, and destroyed the facility by directing the hive ship into it! Its better than C4... :D
Todd escaped, and Teylas baby is all right too. Any, its a boy. :)
Now, im curious about the Weirs story line.
