A deadly powerful creature called Cyberax has escaped from a computer and then suddenly Cyberax the company is born, by no other than Jean-Daniel. He creates a machine that takes over some of the user's mind. Once they have finnished using the Cyberax headset, it leaves a little bit of itself behind. when the person finds out about Cyberax again, as they forget all memories to do with Cyberax, their brains go into overload and they kill themselves. Roland Blatty (the old bureau chief) gets hold of one of these headsets and blows his brain up when Ed jokingly says that he hopes that Roland has had the system checked for viruses. The whole Bureau team are also wiped out when they too discover the deadly truth about Cyberax. Beckett decides that the only way to stop this is to pretend that he has used the headset and had his brain blown up (so to speak) and he is taken away by Cassandra, who is now working with Jean-Daniel. Jean-Daniel realises that Beckett wouldn't do something so stupid (thetvdb.com)
