First off I know the statues are lying so you just reverse what they say. I mind read kaera and i read the note on the ground.
However:
Only one statue will talk which doesn't allow me to deduce which statue is which. I really didn't want to just check a spoiler map to identify them but I might have no choice.
Potential problem: If 4 of the statues won't talk will they acknowledge the name I give them even if I cheat?
I'm sure this has been mentioned before but it's not a very cool bug.
