I'm going to do my best to sum up his story.
In So I ditched my car... Iris first goes on the run after feeling he is being watched by a watcher. Fast foward to early 2007 when IspyIris2009 puts surveillance footage of him on the internet: IspyIris2009 Part 1 and IspyIris2009 Part 2 In I must have missed something... Iris reveals that since he was a hacker that maybe it was the gov't who was following him and take it as a compliment but after seeing the surveillance footage of him on the internet, he realizes it wasn't the gov't. after all. Because of the timing he realized it might be about the last system he hacked, which was the warehouse that Daniel found the epogen at. The files were decrypted so he went back to see if he could crack them. In TIME TO PLAY!!! Iris says he's working on the files but it's apparent things are not right. After the gang was kidnapped Daniel took to the forum to research the drugs they were given. In Dear DB Iris remembered seeing the drug names from a document in a file he decrypted. The document turned out to be an invoice and he reported back to us. He has other documents but apparently can't make sense of them.

I did my best, I think that's the Cliff Notes version. Iris-anything to add? I added it to your lgpedia entry-hope that is ok.
