Yeah when they drop that after the fact in the first episode I was like uh wtf that makes no sense, why would that guy go completely rogue like that for a training exercise? And then the entire reason he gets shitcanned is because the other guy lied about getting the description wrong… are you seriously expecting me to believe that MI5 are doing training exercises like this and not recording all of the communications for analysis and training later?!? It’s idiotic, just no respect for the audience’s intelligence at all.
