Cheeky grew up in the East End and was once everyone's best friend there.
His closest companion was Albert Krag, the gentleman gangster.
They had a mutual affection for a hobgoblin woman named Esme (Albert got the girl).
Once, he wanted to give her peonies, her favourite flowers. 

When Albert's twin sons Phil and Grant devoured Albert, as is Mobgoblin tradition, they seized control.
Cheeky fell from right hand to the very bottom of the ladder. He endured years of low-level work until Ian Beetle slaughtered ten innocent Donloners.
Cheeky killed Ian the Beetle with and was pushed out of the Mobgoblins entirely.

The night at Esme's: 
Cheeky was with the Krag Twins and Ian the Beetle that night at Esme's. 
When everything went wrong, Cheeky was at the bathrooms. 
He believes (or wants to believe) that it was just Ian the Beetle, not the Krags. 
He uses Minor Illusion to make Ian believe that the vial of acid is a heart, for him to consume. 
He kills Ian with a dagger in his neck. 

Alias: 
Deeky Chustbins.
