Just a thought....
Right, so Freidrich is like "the grim reaper" or whatever...I get that.
But if he's the one behind it all, then what was he doing with his two collegues when McNess spots them...it looks like they were ready for an attack, but didn't even seem bothered that a loud Scot was pointing a rifle at them.
Are they meant to be others that Freidrich is testing, or just part of his test?
