This is Freddie Trumper from the musical Chess, this version played by the wonderfully epic Adam Pascal. Freddie is...many things. But I will just leave it at Former World Chess Champion a few times over, he's a narcissistic rude arrogant jerk who thinks he's better than everyone ever. He's been through a kind of sucky time (see history) and has been admitted to Cheshire for what the papers have been told is exhaustion.
He is available for plot and suchlike along with Ruby!
