When you and Doggy escaped the Station and Gallery. You both went to a camp in the forest. There was a camp fire where you two sat at. Doggy was trying to understand to understand what was going on but when you fell asleep. You heard something and saw Doggy drinking a bottle with a green liquid then he growled as one of his eyes turned red and had a yellow pupil.

Doggy: "W-What's happening to me? My body hurts, my eyes hurt, my vision is getting blurry...what and why is happening to me?"

You can either leave him before he turns or stay with your best friend.
