The Fat Controller's grandchildren

The Fat Controller's grandchildren are Steven and Bridget Hatt. They bear a striking resemblance to their grandparents, The Fat Controller and Lady Hatt. Bridgett is the idiot of the two, believing an obviously steam-powered tram to be electric. Steven, or as The Fat Controller calls him, "Homeboi Stevie", is to become the next controller of the island when he passes away...or is inevitably taken down by the loan sharks that are after him.

Stephen
Heir to the Topham Hatt throne. Succeeded his late grandfather Topham at the age of 17 after he was murdered by Daisy for use of the forbidden word, feeble ("Bother!" zzzzappp "Excellent!"). No one knows how he got that position at such a young age. But once he did, he became overwhelmed by the unbelievable amount of debt he had to pay for his late grandfather. He quickly turned to food for comfort, and quickly grew obese, thus molding himself into the new Fat Controller.

Bridget
Bridget is a moron who constantly inquires whether or not something is electric. She has a black boyfriend and also enjoys spending time in breakvans.

Illegitimacy?
Rumor has it that their real father is not their mother's husband, but in fact a tourist who visited the Island of Sodor and was never seen since.
