"Geez, why is this place always like this"

And then he seemed surprised he said that.
It almost looked like he scared himself when he said that.

I think this is supposed to be subtle evidence that he is in fact Mu, and not a replica. Because up to this point, everything can still be explained if he's a clone. Him regaining memories, as shown here, of the AA, can not be explained if he's a clone.
