Tony subsequently met Jenny and left Blackwall after series 3 to run a boutique with her. Colin Parrish (Stephen North; series 3–6) – Colin was the nephew of Red Watch Fireman Jaffa Parrish and joined the watch as Vaseline's replacement. His naïvety and inexperience often made him the butt of pranks and jokes by other members of the watch. He took a liking to Firewoman Kate Stevens and visited her at her house, but was warned by Hallam to stop bothering her. After Colin sent the pump to the wrong address on a 'shout' (which was fortunately a hoax), Hallam extended Colin's probationary period, much to the ire of Colin's mother. Colin became a hero for the first time soon after this, when he saved another firefighter from falling down a lift shaft at a hotel fire. He graduated to full status early in Series 5. He married Zoe, whom he met during a 'shout', (rescuing a bird from a cage), despite her walking out on him after he took her to a football match on their first date. Colin was invalided out of the Brigade after his legs were crushed in Series 6. Kate Stevens (Samantha Beckinsale; series 3–5) – Kate joined the watch as Josie's replacement and she soon fitted in after rescuing a baby from a burning car. She met a volunteer fireman while the watch were on standby in Kent, but soon ditched him when it emerged his favourite pastime was rock climbing. Kate became a full-status firefighter in Series 4, which left Colin Parrish feeling bitter, since Hallam had extended his probationary period. During series 5 Kate met police officer Don, and got pregnant after a one-night stand. She miscarried and transferred to Wimbledon so she could be closer to Don. Stuart 'Recall' MacKenzie (Ben Onwukwe; series 4–14) – Known as "Recall" due to having a photographic memory, he joined Blue Watch midway through series 4 as Tony Sanderson's replacement. He was a very effective firefighter, and acted as Leading Firefighter on several occasions. He was married to Laura and had two sons, one of whom suffered from cystic fibrosis. Blue Watch held a fundraiser so he could take his family to Disney World, Florida. He was injured in the climax 'shout' of Series 4, and also in the Series 9 warehouse blaze where John Hallam was killed, but had lucky escapes on both occasions.
