Development
and Jan Pearson who play Rob and his wife Karen spoke about their on-screen chemistry to websiteDigital Spy, describing their first scenes together, Walker said: "First day on set, in fact first scene it was, 'Hi I'm Chris', 'Hi I'm Jan', right get into bed. So that broke the ice." When asked why they work so well together on the serial, he explained: "I think that we're not precious with our own stuff and we always want to give and help each other and that's nice, and we do row very well." Rob's wife Karen became involved in a memory loss storyline, actress Jan Pearson revealed that Walker had come up with that storyline. Speaking to Digital Spy at the launch of Pentahotel Birmingham, Pearson explained: "The story has been hugely long and it's still going on. I've been filming it for a year now. It was very exciting because it was Chris's idea. I think his original idea was that Karen would be run over by some ex of Rob's. The producers didn't run with that, but they did run with the accident and the memory loss. I was utterly delighted that Chris was responsible for running me over! We now have a very playful banter over who's to blame for the situation!" Pearson also added: "We always knew that Karen and Rob were going to get back together in the end, but the break-up made a nice change from what we normally do. Because it was Chris's storyline and his idea, I really wanted to give it my best shot. What Chris came up with was very detailed - it was extraordinary. If the acting career doesn't work out for him, I think he's got a really good shot as a storyliner"
