Dean Lennox Kelly returns for the landmark 100th episode of Shameless, as Mickey give Mimi an ultimatum: either the new boiler goes or he does; and suddenly Micky finds himself on The Jockey sofa.

Kelly tells Marty to keep his distance but it's easier said than done.

There's uproar in The Jockey when Frank pockets Cynthia's scratch card. And when Cynthia is assaulted, Frank becomes the prime suspect. Carl kicks off against the accusers, but Kelly shows Carl CCTV footage of Frank near the crime scene. Frank remembers nothing but scratch marks on his chest tell a different story.

While Frank hands himself in, a distressed Carl seeks to prove his dad's innocence and phones Kev Ball, who returns to the Chatsworth like a knight in shining armour.

New video footage jogs Frank's memory, but puts him in a stickier situation. Can a deal be made with gangster Growbag Macready? Frank's fate rests in his hands.
