I can't be the only one who thought about this the second they saw the tree. There is a man behind the tree, but not the one you know and see. Wait before the thing you know, and eventually the man will come and show. First go between the rooms with red, and you'll appear at the leafy bed. Next you'll find some weird graffiti, near the house of a salesman which once had a treaty. Third, choose some very specific dialogues. And hear out the man who monologues. Lastly, enter the stone chamber. Reveal the poor children who where once in danger.
