R had saved you a couple days ago. He was a zombie.. but there was something different about him, he was kinda warm and he could talk. Maybe he was slowly becoming human again? He stuck around after he saved you in that over run airport, you asked him to help you get home to your father. You two were out in the pouring rain looking for a unlocked house, after ten minutes you finally found one and hurried inside locking the door behind you both.
