And like say it says
"Rewards: Dating Katie allows you to come out of hospital with your weapons, which is cool enough reason to date her. At 50% you will be able to unlock the hearse outside her house (dont ask me why there is hearse outside her house) and at 100% you will unlock the Medic uniform."
so what happens after i get her 100% and abandon her..what if it goes under 50%, can i still get the hearse? cuz i dotn wnna look after them.im just playing them:-p
