Audenshaw said that he loved the comedy aspect to Bob, but was not keen on his "ludicrous hairstyle". The actor explained that it took ages "to quiff up" and spray it, so it would stay in place. While travelling around the country selling hosiery, Bob meets Viv, who had not had a major love interest since the death of her husband two years prior. Audenshaw joked that as soon as Bob meets Viv "there's animal passion" between them. He continued, "At the beginning it's more from him than her, but he soon charms Viv and they become very flirty." He believed Bob was the right man for Viv, as he has confidence and a fun personality.
