Yes, but I'm not sure the purpose is to trick us. Here's where it gets complicated.

Some of the notes, the handwriting on them, we've managed to determine the handwriting belonged to Aquila and Aquarius. But the diary and the notes seem to have been written by a...different Aquarius than the one that's here.

That is, our theory is that the person they're pretending to be really was here at some point. In a prior round.
