Warren's early storylines involved his dealings in many crimes such as drug dealing and protection rackets amongst other things, affairs with Mercedes McQueen (Jennifer Metcalfe) and Mandy Richardson (Sarah Jayne Dunn), murdering associate Sean Kennedy and ex-fiancée Lousie Summers and feuds with both Clare Devine and Calvin Valentine (Ricky Whittle).
