Liam first appeared on "Coronation Street" in August 2006 when he and nephew Ryan (Ben Thompson) visit his sister Michelle at the Rovers Return Inn. Whilst there he overhears Adam Barlow (Sam Robertson) discussing his unhappiness running local factory Underworld with his half-brother, Danny Baldwin (Bradley Walsh). Liam calls on his wealthy brother Paul (Sean Gallagher) to help him purchase the factory. The brothers manage to convince the teenager to sell his 40% share for £80,000, less than half its value. Liam also briefly romances Frankie Baldwin, putting himself in a difficult situation with Frankie's husband and the Connor brothers' new business partner Danny.
