"when i'm bored, i eat rocks" ..Clue ?

[Arthur Fenix]

I just notice something that was in my face all the time, but i just start thinking about it right now.

Every time you resume playng after you idle, the Shade say something...and every time it is actually reference or a clue about the game! (sorry if my quote arent EXACTLY the one in the game)

"i dream of an hall with white colum" = the hall of eternity
"I dream i heard a scream and i fell from very high" = Suicide ending
" I dream about a well" = well ending
"bla bla bla i m afraid of darkenss"= to pass the dark part
"something has fell from the sky"= something has break in the kingdom and you can go and check
"i never felt so alone"= the state of the game

and so it hits me.... "when i'm bored, i eat rocks".. since EVERY other quote is actually talking about the game, or give games clue,... how about this?
At first i though was a funny joke, but now i dont think it so much.

there are actually rocks around that the game call "rocks", like the ones that block the exit to the outside world. but multiple time i left the guy alone and bored in that kind of places and i never seen him eating anything(i was actually waiting to see if somebody will come but still...)

Myabe, like most of the other stuff, a certain time is needed, maybe even a certain ammount of days.. but im not sure

what do you guys think?

He just eats rocks bro. Leave his eating habits alone

no secret with the rocks one. Further in the game he'll say other silly things too!

The exit to the cave is blocked by granite. Though, I don't know why a secret ending would exist there, since it would likely result in the exact same outcome as the Well endings.
