But I'm already in her pants, so the desire to help her comes from being both a lover and a friend who cares about her, and even she wasn't a lover, I'd still want to be a supportive friend to her because I like her.
You can support someone as a lover and/or a friend because you care about them in their respective capacity. If Wendy was a friend, I'd support her too because that's what friends do. It doesn't have to be for sexual gain because Mona is a character who I acknowledge is somewhat attractive, but I have no interest in her sexually yet still would want to help her if I could.
