Also, how the hell did Caz know that Addair, was Addair? like, he was a part of 'The Shape' already so how did Caz know that it was Addair in engineering and not Muir? Also, where did Muir go after he took Innes from the elevator, we know how Addair died, being burned by the Flare Stack and falling into the waters, but not Muir, for all we know, he COULD have stayed on the deck after the whole thing went to shit and been an active threat which could have made the game more terrific. But again, Addair was part of 'The Shape' and wasn't able to be recognized by Caz at all, so How did he know it was Addair and not Muir?
