He is introduced after Booker brings the player to his house on Renbow Island. Nick works as an apprentice in wood craftsmanship under Booker's care, a mentor who is strict but sees great potential in his pupil. Nick also has a habit of repeated pessimism, often thinking too critically of himself or the conditions of others, which Booker jokingly refers to as "daynightmares". When Pichu's ukulele is broken by Pokémon Pinchers, Booker sends Nick to retrieve wood from Dolce Island, asking the player to escort him. While getting the wood, Nick accidentally steps on a group of sleeping Sunkern. Later on Nick will upgrade the ukulele Pichu's instrument making its assist last longer and more effective. He later helps Booker repair the Ranger Union's ship, The Union, after the player returns from Blue Eyes' submarine.
He built the bridge in the Latolato Trail, which was christened "The Over the Creek in the Green Forest, the Red-and-White-Striped, Wonderfully Crafted, Raikou Safe with No Creaking, Renowned All Over the World for Connecting Yesterday and Tomorrow and Proudly-Built-by-Nick Bridge" by Ralph and Nema.
One of Nick's pessimistic "daynightmares" actually came true: At an early point in the game, Nick says the player's partner has been tied up with a rope. Later in the game, this is revealed to be true.
