Trey's twin sister was called Trissy. She was once like Trey, a cocky but not so much a troublemaker. But otherwise she liked the kind animals that are so friendly and polite. She thought of course that all the animals, including the animals of farthing wood are so friendly and polite to all the stags all the time. But not really all of them, exactly.

But after Scarface died, Trissy suffered some tragedy, which would lead to Trey despising all the other animal inhabitants. She was out by herself alone in another part of the forest that day. That is, inside the blue foxes' territory. Trissy is not afraid to enter their territory, since she was a young-adult doe, and can handle it herself, of course.

She was standing by the meadow just near the stream, she was eating the grass and drinking some water. But then suddenly rustling sounds were heard nearby. Trissy's ears pricked up and listened and lifted her head and looked around a little, to locate who it could be. But as soon as she turned around and walked a little away from the stream, a loud meowing was heard.

Trissy looked up to her right and saw something that made her eyes widen with fear. It wasn't long before The Great White Stag and three other deer managed to find her, but a little too late. When Trey stubbornly wanted to see what she looked like and what had happened to his sister, his anxious mood turned to both shock and rage when he saw what was left of her body.

When Fox visited The Great White Stag in the stone circle and heard what had happened, he was so deeply saddened by Trissy's death. Even though Trey is too arrogant and narcissistic a stag, he couldn't help but feel sorry for him. That's why Fox tries his best to make him become a little more kind-hearted and friendly stag, instead of becoming wild and bananas, driving all the innocent animals away from White Deer Park.
