Socket is a character in Professor Layton and the Last Specter.
Both he and his sister Wren denied any knowledge of the black market when asked by Professor Layton, Luke, and Emmy. He later took part as one of the Black Ravens when Emmy gave chase. After the trio find the black market and talk with Crow, Socket and Wren can both be found at Highyard Hill, just outside the gates of Barde Manor. He remains here for most of the game.
In the post-credits cutscene, he can be seen beside the other Ravens and Arianna, now being a friend of hers.
