Bro, zombie pussy are cold and rotten...Resident evil references? So, how about doyle's mother and sisters coming back to life as zombies and the MC catching them? Zombie pussies are hot.
Please rise your hand if you would like to a ghost busty team Poon aside, this could be introduced in Lucile's story line. She is waking up during the night because she hear strange noises, it wouldn't be so farfetched if during of that night she mange to see Doyle in wandering ghost form. A similar scene could lead Lucile to further investigate the basement and then call the police after she find the Doyle's bones.
