That scene round 06:00 where the guard runs round the corner doing his little battle cry and then it just stops and carries on a moment later as 939 mimics it is actually pretty cool. Same when him and the other NTF are running away and 939 catches and mimics his voice without us seeing. If I was playing that, both of those events might have tricked me.
