i imagine driver with a mixed coat but a huge white patch on his upper body as symbolism to his jacket and for luke i see him as a mostly black coated wild dog with very spare brown and white throughout but with a white patch on his chest for his heartthrob tattoo
I mean I personally think fanfic doesn’t need to follow canon. A lot of the time I love reading stuff that the canon characters would never do. And sometimes I love reading a fic that has great characterization really close to canon. Love the diversity of interpretations, tho!
