So FERO has spoken, and seems very determined for the true origins of the Spartan II program to be made public; even in the face of what is brewing in deep space which seems to threatening everything. But who is FERO? This is my list of potential suspects with pro’s and con’s as to why they are/aren’t
Halsey - seems to be the favorite at the moment. Certainly has grievances with ONI, knows everything about the Spartans and certainly has the ability to bypass security measures and access pretty much everything. But why would she want to risk her Spartans being turned on by making it public? She knows how they are regarded in the military, especially in the early days. Would she want to risk seeing that animosity spread?
Cortana - yes, I know she’s been confirmed dead in multiple sources but she has the knowledge and ability of Halsey. Plus, is it beyond the realms of possibility that part of her survived the destruction of Didacts ship? ONI would have definitely salvaged every last piece for study. Has Cortana broken out? And whilst admittedly she would be quite broken, what does she gain?
Osman - definitely holds a grudge against the Spartan program, can get the details out and pin it all on Halsey and previous administration. If it was revealed that she was a Spartan, she can play the sympathy card as she “washed out”. May not be able to do the hacking herself but would know people who can.
Petra - She wanted the Master Chief story really bad, was pretty angry when Ben got it but suddenly wanted to pull out when it got too much? Doesn’t sound like the Petra who would walk into an Elite bar and shoot one of them to command respect. Definitely has contacts who can hack (Mshak anyone?) But why would she want the story out without getting the credit? Possible insurrectionist sympathizer?
Mshak - he can’t be got hold of shortly before FERO makes “her” appearance? He has access to pretty much all the un-secure chatter, he knows what’s brewing in deep space, not beyond the realms of possibility he’s stumbled on the Spartan II a while back. He also knows he has zero credibility so when he found out Ben is doing a piece for ONI on the MasterChief, he seized his chance. Not sure what he gets out it though.
Relative of a Spartan - we know there is at least one relative who knows what happened, could it be them or possibly another? They would likely want to see ONI fall hard for what they did and may have contacts to bypass security and get into ONI. But why not just release the data themselves? Why use Ben?
Isla Zane - on here purely because a) she’s female, b) holds a grudge against ONI and with the insurrection and c) insane
Someone else entirely - no idea who, new character to come in ready for Halo 5
Who’s your money on?
