Avenger 2.0

Avenger 2.0 is the ninth episode of the seventh season of Stargate SG-1.

Plot
Dr. Felger and his assistant Chloe are working on some kind of weapon at Stargate Command. Felger tells his assistant about the time when he rescued SG-1 from He'rak (see "The Other Guys"), when suddenly Col. O'Neill and Major Carter appear. He presents them his new weapon, which should be used one day on X-303 as an energy weapon. However when he activates it burns out and causes a power failure on the whole base. Afterwards Felger talks with General Hammond about his work and Hammond tells him that although Felger assured him that he will give them something, he created nothing in the last six months. So Felger tells him that he is working on something and Hammond tells him that he has 24 hours to present his creation.

Afterwards Felger talks with Chloe who tells him that he can't create something in 24 hours, however Felger tells her that he has Avenger and starts to work on it. On the next day he presents his idea of a computer virus which will cause chaos in the Stargate system to Carter and she is interested. Afterwards she decides not to take part on a mission with SG-1, although O'Neill is not interested in Felger's work.

While Felger works on a diorama at home, he is visited by Carter, who tells him that the General allows further research on the virus and that she will work with him on the virus. They then start to work on it at SGC and after some time decide to test it on a real gate in Ba'al's territory and wait on an answer from a Tok'ra spy. During the test however they contact SG-1, who missed a scheduled contact. O'Neill tells them that they can't dial the gate and they think that it is Felger's fault. While they search for the cause of this problem, the Tok'ra contact them and report about a series of malfunctions in the gate system. Afterwards Carter gets some data and finds out that the virus started to spread through the gate system thanks to the periodic correlative updates which compensates for stellar drift.

Afterwards SGC calls back all off-world teams but several teams can't come back because the entire gate system has gone offline and now only SGC can dial anywhere. Later O'Neill reports and tells them that the negotiations in which they were taking part went awry but then they are attacked and the contact breaks down. Afterwards Carter, Felger and Chloe work on a solution of the problem and Carter is informed that Ba'al started to attack the other System Lords since he has the largest fleet. Afterwards Carter talks with Felger about the situation and when she tells him about an incident from a few years ago he comes up with a solution, which however doesn't work.

Later Carter informs Hammond that Felger has left the base since the pressure has become too much. Carter finds him at a bridge and starts to talk with him about the problem and they again try to find a solution. They then conclude that they have to go to the planet to which they sent the virus and both Felger and Carter volunteer to go there. Afterwards Felger says goodbye to Chloe who kisses him.

Both Carter and Felger then leave for the planet, where they start to work on the DHD. However Felger soon finds out that Avenger was tampered with and Carter concludes that it was Ba'al, since he gained most when the gate system went offline. Now Felger has to work on a new antivirus system when suddenly Jaffa appear, whom Carter fights. Suddenly an Al'kesh appears which fends off the Jaffa. Afterwards O'Neill and Teal'c ring down and are enthusiastically greeted by Felger. Felger is then able to solve the problem and they return to SGC, where they inform Hammond about what has happened.

Later Felger daydreams how Chloe kisses him passionately when suddenly O'Neill and Carter appear and see them. Carter then attacks Chloe and while the two women fight Felger's dream is disturbed by Chloe and they go back to work.
