As the film stands, when Roger and Liz appear on screen, the audience has no idea what their relationship is because anything establishing that was cut. Nearly everything that illuminated character was cut. So, even if Gordon Russell and Sam Hall had somehow added a wink about Vicki for the established DS audience, chances are DC would have cut it or never even shot it because, as I've lamented before, he was mostly concerned with getting every bit of biting, ripping, tearing, killing, and blood and gore that he could get on screen...
