Gus is an ordinary guy, Micki is a trainwreck: logical couple
Gus: not a bad guy, not the nicest guy. Caught up with himself, a little opportunistic, but not evil. Lashes out when his ego gets bruised, but tries to be reasonable.
Micki: a burned cookie. Love/sex/drugs addict. Manipulative. Extremely needy. Not pure evil either, but more a walking 'condition' than a person.
The fact that they are somehow 'on the same level', says something about the way we evaluate men and women.
Micky gets one starting point for just being a woman. Gus gets a point for being 'ordinary', which makes them equals.
