This trophy can be missed and is the beginning when you enter Castel at gunpoint.
As George, feed the following items to the goat:
- Provenance
- You then need to stand by the apple tree and dodge the goat's charge and this will allow the bruised apples to fall, pick them up and feed the goat
- The Rich Tea Biscuit (The goat will thank you)
Progress through the game normally until you gain control of Nico.
Return outside the Castel and approach the goat where you first encountered him and interact with him. You'll earn the trophy after the dialogues finished.
