Describing Dot, Brown has said, "I love playing her – she's a strong character. Dear old Dot, she's got strong moral views and odd religious beliefs, but her heart's in the right place. She has that awful worried expression on her face the whole time". Brown has noted the changes within Dot since the show's inception, saying that initially Dot was sharp and selfish, but since her character remarried in 2002, she has gained security and has "no reason to have the hypochondria she had in the past [...] She's become more caring over the years. She enjoys the company of young people. She loves her church. She can get in an anxious state – I like it when Dot's hysterical! She's also amusing, mostly because she doesn't realise she is".
