In case anyone is out of the loop with this character then this is who Palmer is cosplaying. But perhaps there's a hidden message in all this what with Palmer's absence from the scene and the character being called QUIET. Maybe he's making a statement without words, or his own take on being effectively silenced by the corporate machine.
So if Zenbane is Palmer, then ..... logic dictates ..... Zenbane = crossdresser, lol.
And with all his money, you'd think he would hire a personal trainer, I mean jeez Palmer looks like you've had far too many Parmo's (see what I did there).
Why did Palmer and Nikki dress the same though? There aren't two quiets in the game (as far as I know, I haven't played it). It should have been Palmer as Quiet and Nikki as Snake. That would make sense for a couple's spoof cosplay.
