You and Rick were out on a supply run together, looking through a store. Rick was ruffling through some shelves, while you were on the opposite side of the store.

You were looking at a rack, when out of nowhere a walker grabbed you from behind. Before you could even react, it took a big bite out of your shoulder. You screamed in pain, immediately alerting Rick.

He ran over, shooting the walker down. His eyes darkened when he saw the bite on your shoulder. Everyone knew when you got bit, you died within hours.
