Bazzi has been targeted before, and the write up specifically said that "he'd been waiting for someone to fire since this damn thing started".
To me that rules out Bazzi.
The first paragraph reads.
The magnificently mustached man sat and looked out the frosted windows of the cabin they'd liberated. Despite initially being uninterested in this partnership, he'd lost all desire to break free.
To me that reads as two separate sentences, but starting off with the mustached man makes it sound like that POV carries over into sentence two.
Really it's from the second characters POV who is sitting there waiting to be targeted while his "partner" the man with the mustache is sitting, looking out the window.
Therefore
RHCP - JM the 3rd
Fred - Freddie's Mustache
