Dexter "Dex" Walker is a fictional character from the Australian soap opera Home and Away, played by Charles Cottier. He made his first screen appearance during the episode broadcast on 30 July 2009. Tom Green originated the role, but when the Walker family returned in 2010, Cottier took over the part. Cottier quit the role in early 2013 and Dexter made his last appearance on 13 November 2013. Creation and casting
In July 2009, it was announced that the Walker family would be introduced to Home and Away for a five-week guest stint. Actor Tom Green was cast in the role of Dexter Walker, the son of Sid (Robert Mammone) and Jody Walker (Victoria Haralabidou) and brother to Indigo (Samara Weaving). A year later, Dexter, Sid and Indigo made a permanent return to Home and Away. Green did not continue in the role of Dexter and Charles Cottier was cast instead. Cottier auditioned for the role on the Gold Coast and he received a call asking him to come to Sydney the following day. Shortly after that, he learned that he had won the role of Dexter. Of his casting, Cottier stated "I'm so happy to be joining Home and Away. Moving from Brisbane was a big step, but the cast and crew have gone out of their way to make me feel at home." In 2011, Cottier admitted that initially he had been "slightly intimidated" about taking over the role from Green. Cottier revealed "I sometimes hang out with Tom Green - he's a really nice guy - but I chose not to watch what he'd done. I think Dex is quite a different character now, too." Development
Upon his return in 2010, Dexter has a "different personality". Of this Cottier said, "I think he's more mature, from what I've heard. And he's hilarious. He's funny." He added that Dexter "doesn't really turn it off". Channel Five's soap opera reporting website Holy Soap describe him as a "quick-witted and sensitive schoolboy". Holy Soap also add that Dexter is "very funny and sarcastic", but he loves his family deeply. Seven Network comment that Dexter "wears his sense of humour like a suit of armour". Describing the character in an interview with the official Home and Away website, Cottier said: "He's quite a strange boy. He's funny and quirky and I think he finds it a little bit difficult to make friends." He added that on the inside Dexter is "quite a sweet person and quite vulnerable". Following his return, Dexter falls in love with Sid's new partner Marilyn Chambers (Emily Symons). Cottier told Inside Soap magazine that the storyline was embarrassing because of the age difference between the characters. Of this, Cottier explained: "It was one of the first things I read about the character, and I was kind of embarrassed, but excited to do it! Not every guy comes to Summer Bay and falls in love with a woman 20 years older than he is. My friends gave me grief about that! I got to work with Emily Symons though, and she's fantastic." In July 2013, Cottier's co-star Teri Haddy (Rosie Prichard) confirmed to a TV Week reporter that he would be leaving the show, along with Rhiannon Fish (April Scott). Haddy commented "I think because they have both been on the show for so long, they wanted to start a brand new chapter. I want it to be a really positive ending for April and Dex, and an open-ended one." Storylines
