What was supposed to happen in Medea but didn't, due to: Continuity problems, frustration, lack of time, and outright laziness.
-The monster is killed, but not before she infects Kenny, the lead scientist, and dozens of drones.
-Sheppard kills all but partially changed Kenny during the escape to the dart bay. Jennifer is scratched on the way.
-McKay convinces the pilot to aim the hive (which has turned, jumped into hyperspace and is back at the planet at Todd's orders as soon as word of the monster's escape) at the planet's stargate to crash the ship and destroy the infected, and prevent survivors from spreading it to other worlds.
-McKay with the pilot radio Sheppard to rendezvous at the dart bay.
-The group finds Todd cornered by a now fully transformed Kenny, suffering from a nasty abdominal wound. Sheppard kills Kenny just before he can finish Todd.
-Jennifer manages to rig a bandage from her tee shirt to keep Todd's innards in their right place. She and Sheppard help him to the dart bay while McKay fires at two desperate, injured wraith who intend to feed on the group and take the ready dart. They manage to feed on the pilot before the bullets stop them.
-With Todd in the cockpit, the team escape the hive.
-Todd lands the dart on a nearby world with a stargate, dematerializes the team so they can dial Atlantis.
-Jennifer convinces Sheppard to let Todd come with them so she can check his injury, which has not healed. Todd nearly dies after being moved from the dart to the stargate.
-Story ends with Todd escorted from Atlantis, stitched up, partially healed and heading towards a Wraith friendly planet to feed. Jennifer is still conflicted about her feelings for McKay and her affair with Todd. Their relationship is strained but she agrees to join him for lunch the next day.
