Now that the game finally started, it seems Zelda showed up at Hyrule castle during the blood moon! I have to go there investigate; but first, I after ~6 different people across Hyrule told me Robbie has a camera, I asked and it seems this is another feature that will be unlocked. I just have to follow him to the Depths.
A little late, old man. The whole place is lit up and explored; but I guess this quest is intended to show not all characters are as familiar with the Depths as Link.
Robbie knows that Zelda is not the real one, it seems.
Also, the game teaches me, very late, how to throw items and how to attach items to arrows. This information would've been appreciated at the beginning of the game.
