I never pictured Mara with an accent. I always thought she would talk like Luke, but it makes sense that if she grew up on Coruscant that she might pick up a slight accent. Gods! I hope if EP7 comes out and Mara is in it she doesn't have some weird accent like, "Blimey! I am gon'a kill yew Luke Skywalker. Nuff said, yeah? Awright geeezzaa! Why is i' what I am talkin' like a David Hockney when I am supposed ter be from a galaxy far, far away? Sorted mate." I used an AMERICAN TO COCKNEY translator to get that so don't blame me if it doesn't make sense.
