No.2 of It's Your Funeral once told No.6 that the Observers do see and hear everything. Well if that's the case, why didn't any Observer spot No.6 following the doctor-No.14 through the village to the secret laboratory in the woods? Or Curtis having a fight in No.6's cottage during The Schizoid Man? They also failed to notice No.6 pouring away that drugged cup of tea in A Change of Mind. If Observers had been doing their job right, then certain situations would have gone in favour of No.2, instead of against him, or her.
