Love is a show filled with broken / terrible people, so I’m going to guess right now that she simply enjoys lording over people, making them feel bad about themselves and then tossing them aside.
For that matter, why is Sherry going to be willing to let Love in if she doesn’t really want her around?
Or, is this just going to be one of those crazy happenstances, like Joe finally finding someone who really loves him for all that he is?
I have a sneaking suspicion that Love won’t toss easily, though.
