Walker came to 'Hollyoaks' after he was released from prison. He immediately contacted Brendan Brady, a crook whom he offered to team up with.
What no one knows is that Walker is an undercover cop & only sticks close to Brendan because he seeks to take revenge for the death of his younger brother.

He is 6'1 tall, 33 years old and identifies as male. He's got blue eyes, shaggy brown hair, and often switches between clean shaven and a stubble. He's cunning, manipulative, vengeful, and aggressive.
