I suppose episode 2 started to imply these things? When the servants saw dead-Kanon, we saw him on screen and of course we know that scene is fake since it can't be real.

But they did go to the parlor and say "We saw Kanon!" which, since it's in front of Battler, means they really did say that? Since things that Battler experiences are not lies...? (Theoretically) So we can assume they a) saw something that they were sure was Kanon or b) lied.
