I actually see them being frenemies/rivals. They probably would respect each other, but still be competitive. And I totally see that happening! If you've read Lulu's page you'll know that she has a lot of fake "friends", but since Viv seems to care for Lulu, she'd do everything in her power to keep their friendship. I'm sure Lulu's been introduced to all the future musketeers, but will probably be especially close to Viv. In fact, one of the two probably requested the other as a roommate.
