Debbie's relationship with the rest of her family is generally good. She views her siblings as her dependants and generally supports them through their various misadventures. The rest of her family generally recognises all she does for them. She's particularly protective of and very close to her younger brother Liam. Her relationship with him seems to border between surrogate-parent and partner-in-crime, as she has frequently enlisted Liam's help with some of her past schemes. These include faking Liam's kidnapping when Frank wouldn't admit that he hadn't won the lottery, and she once entered him in a modelling competition, which she wanted to keep a secret from Monica. She can also be seen to forge strong relationships with other characters, notably Marty Fisher (Jack Deam) and Mandy Maguire (Samantha Siddall), she also tends to come up with numerous money-making schemes to provide income.
