1) No bro she goes all the way - you sure you have the steam api unlocker thing functioning?
2) I'm biased against girls that are too easy, yeah she has a heart of gold and I try and protect her from her family as a good friend during playthroughs, but as for romance, I won't be the one jumping on that grenade.
3) Attractive, quirky, intelligent, and outside the main 'popular group', she provides an excellent break from all the drama. Again, are you sure you have the full game installed? Because she becomes a fairly major character in ep2-ep3, probably has more scenes than many of the other girls on list.
4) Agreed with all you said, but what she does, she does well. She's the 90210 girl with the attitude to match, and it all fits. I like her because there's no dishonesty there. I mean she's dishonest, but you KNOW she's dishonest going in. She only likes you if you're a yolo douchebag, so she can be fun on those kinds of playthroughs.
