As we all know - Tyndall has reported that some type of catalyst will reactivate the Smith Virus within---one week, correct? And we also know that Seraph's gone 'nuts', knocking people out and such.
I think I may actually have an explination for this, a good one at that. It's possible that all the Operatives that were infected before the System reboot might have a small ammount of the Virus residing with in them. And seeing that the Smith virus is coming back due to an unknown catalyst, that small ammount of the Smith virus that resides in them just might possibly 'ignite', so to speak. And if this is true, those certain operatives that were infected might be attacked by Seraph for a reason: To get that Smith Virus removed.
The reports of Seraph knocking operatives out also gave some information saying that Seraph did some type of ritual to remove the code from the Redpills - this code is probably the Smith Virus. -If- I'm correct that means that this cancer will move to Seraph in mass amounts, causing Seraph to be infected. Possibly the only person infected if he extracts the rest of the code within a week.
This is alot like cancer, spreading, and killing all in it's path. Please, don't attack Seraph. He's attacking us for a reason... ((If you have any objections go ahead and try and prove me wrong, I've got an explination for probably everything.
