collapsed and he fell . Carole 'Doris' Webb (Zöe Heyes; series 9–10) – Liverpudlian Carole became the Watch's new Sub Officer in Series 9, having previously worked as a Health and Safety official. She was married to Martin, another firefighter, who had had to retire from the brigade after being run over by a car whilst drunk. She was attracted to both Firefighter Jack Morgan and ADO Patrick Davis, and had a brief relationship with the latter, but she left him when she found out he was still married. In the final episode of Series 10, she was told she could remain in Blackwall as Sub Officer. However, the character did not appear again from Series 11 onwards, and no explanation was provided. Leading Firefighters/Crew Commanders Malcolm Cross (Rupert Baker; movie, series 1–5) – Public school-educated and articulate, Malcolm was often the instigator of pranks at the station. He struck up a relationship with Samina during an inspection of a clothing factory, impressing her by speaking Punjabi, and was devastated when she was killed in a fire. Malcolm blamed himself for Roland Cartwright's death, since he had ordered him to use his breathing apparatus in an underwater rescue, even though it was unsuitable for such use. Malcolm received a commendation for bravery in series 3 after rescuing a man who had been buried alive at a building site. He took on new flatmate Helen during series 4, and they eventually began a relationship. He bid final farewell to Blackwall during series 5 and relocated to Brussels with Helen. Geoff 'Poison' Pearce (Michael Garner; series 6–14) (Later Sub Officer Pearce) – Pearce joined Blue Watch as Leading Firefighter in series 6 following Malcolm's departure. He had previously been a Sub Officer in Bristol, but took a temporary demotion to join the London Fire Brigade. He was nicknamed Poison, for his habit of spreading malicious gossip and rumours around the station. He was noted for his incessant grovelling towards senior officers by offering them cups of tea, and for his irritating catchphrase "Chop-chop!" when giving orders to the other watch members. He was married to Patti, but they divorced when she had an affair. He later met Fiona, eventually marrying her and having a daughter. Pearce was wracked with guilt after Hallam's death and considered requesting a transfer, but he stayed and had become the watch's permanent Sub Officer by the start
