So, assuming she spoke to him a lot, visited him then it is an influence she'd have had her whole life.
My Mother was from the Northeast of England but was actually RP from University in London (it was considered part of the education back in the 1950s to get rid of regional accents). Her parents however, never lost their durham accents, even after moving down to Essex, which is where I was born and brought up. Their influence (my Granddad lived till I was 25) along with contact with my other relatives from that area means that i have a slightly hybrid accent which many find impossible to place. As others have said, it is more certain words or expressions which are Northern and inflections. This gets more pronounced when i go back up there for a visit or am in conversation with somebody from that area.
So, if I were in that House, in all probability, it would increase because of Marnie who is from a very similar area, maybe 15 miles further North. Even though I actually live fairly close to Lewis, I don't sound like him, i don't have that TOWIE accent and that is because of my familys influence growing up.
Some people do just have a good 'ear' and will pick accents up really easily, whether they want to or not.
