That's true. I would love to see Phoenix using evidence to combat a spirit medium to save the defendants. I don't see that happening though, especially if Maya comes back for more than a single case. Of course we know so little it's be silly to write the game off. I'm just expressing a bit of concern based on what they've said and shown so far.
I know, that's why I think it'd be a regression if they went back to having Phoenix get help from the dead.
Nothing wrong with blasts from the past, but I get your point. I really do like Hix's speculation though. A theme of the natural vs. supernatural would be dope.
