Tony wears a long yellow coat with three buttons, and a blue scarf. He also wears blue shorts, white socks and green shoes.
He is protective and loyal to his family. This is shown as he started the rumor about Arianna being a witch in order to protect her while she was ill, and disguising himself as Seamus.
One year prior to the events of Last Specter, Tony's father, Evan, died from falling off a cliff. Misthallery's police chief, Levin Jakes, ruled that Evan's death was suicide, along with support from the only eyewitness account made by Clark Triton. He too became reserved and bitter like his sister.
In order to protect Arianna from those who spoke ill of her, he disguised himself as the family's gardener and her carer, Seamus. Whenever he heard anyone badmouth her, he would paint the "witch's mark" on their house.
When Professor Layton, Luke, and Emmy, try to enter Barde Manor, they were turned away by Tony, who was disguised as Seamus. After they find the secret entrance and briefly speak with Arianna, Seamus finds them and orders them to leave the house immediately.
Later during the day, Layton, Luke and Emmy are told by Mimi that Seamus was seen going to the market by the canals in a boat. When they ask around, nobody says that they have seen him, but instead they saw a young boy, confusing Luke and Emmy.
Layton eventually works out that Seamus is actually Tony in disguise, and reveals this at the lakeside at Barde Manor. Later on, when Descole's machine begins attacking Misthallery, Tony runs with his sister to safety. He too can be seen crying at Loosha's side in the Golden Garden when she dies.
Tony is last seen in the credits, taking his sister, Arianna, to see all townspeople celebrating her and Loosha's bravery.
Some fans claim he resembles a child version of Milo Thatch from Disney's Atlantis: The Lost Empire (2001)

Living only with his older sister, Arianna, whom he is devoted to, Tony knows very little of the outside world. Impulsive and touchy like his sister, he set out to punish any who spoke ill of her, skilfully disguising himself as the old gardener Seamus.
- US Version
The gardener of Evan Barde's mansion, Seamus turned out to be Tony in the guise of an old man. Every aspect of the disguise, down to the most minute detail, was so accurate that not a single person he met was aware of his true identity.
