In the fourth episode of season 1, Ms O'Flaherty overdoses on some pills after having an abortion. Unfortunately, the building's on fire at the time. 5F rappel down the side of the building and save her.
When 5F plays cricket against the staff, Steve takes frequent advantage of the retarded boy's naivety, including hitting all the balls to him because, "he's useless". The boy later catches Steve out, winning the game.
