Wow this is getting weirder by the hour
My theory so far: The Gs are handpicked and therefore most likely really strong. I'm now pretty sure that Alen is one of them as well as Osman.
They know they have every advantage on their side, and consequently decided to pull shit like Osmans long post, which is a bit risky, but can perhaps give them the D and BG, pretty much our only hope, sooner.
The whacking of Zach also makes sense in this process of thought. They know that they got most of the experienced players, so they'd be looking to eliminate the remaining experienced Cs first. They could also assume that Zach got a special role as they are handpicked, making the deed even more lucrative. Moreover, it created confusion and gives them time, which is defenitely on their side, and opens up so many possibilities and red herrings for the Cs to follow.
My conclusion: Alen (can't make it bold on my phone)
