The same way I knew Naruto was going to use Oodama Rasengan on Itachi in Shippuden like weeks before the episode Naruto left with Jiraiya. The same way I knew Ichigo was a Vizard and knew the other Vizard when they were still at the Bounto episodes. Incidentally this is also the same way I knew the story to Claymore before it even hit the shelves in Japan.

Go read a Shadowrun book and you will find out how I can know about works in progress and how they are going to pan out. I'll give you a hint he's what they refer to as a contact but hes a special kind that sells two things one is hardware of all kinds and the other is information.

Now tell me what is his profession named?
