HOW DO I FIND THE PROOF THAT CALVIN NEEDS?
There's not much more to find in Ate's room.
--
Apart from all these mirrors. Why is Ate interested in her face so much?
--
Actually, there is somewhere you can see her face.
--
Go to the portrait wall in the library.
--
Compare with the memory of Ate in your inventory. The memory is of the woman you have met at the castle, the portrait on the wall was taken of Ate at some other time.
--
Do you see it?
--
The birthmark is on the wrong side.
--
Tap the birthmark in the portrait to confirm.
--
Now go to the staff dining room to confront Fake Ate.
