Trigger appears as a teenager in the "Only Fools and Horses" prequel series, "Rock & Chips". He is a relatively minor character in the prequel series, but in ""The Frog and the Pussycat"", Violet Trotter, Del's grandmother, mentions Grandad's affair with Trigger's grandmother, Alice Ball. This is the first time in the "Only Fools and Horses" franchise that Trigger's real name is mentioned. At one point in the pilot episode, Reg asks Del and Jumbo if Trigger is mentally OK, since he once spotted Trigger laughing at a television set which was turned off.
