It was pretty late. You had convinced Joel to let you tag along for supplies. As you sneaked out of the QZ one of the guards catches them and makes you both kneel while he checks for infection.
"We've been here for the past 3 months, we're not infected." Joel said as the FEDRA officer checks Joel.
"I don't care, it's protoc-" the FEDRA officer says before an infected jumps on him from behind.
You and Joel throw yourselves away. Joel shoots at it but it isn't doing anything. When the infected finishes with the officer it turns and jumps on you. You fall and try to cover yourself from a bite. When Joel takes a clear shot the infected falls on you.
You crawl away before rummage for your flashlight. When you light your forearm you look up at Joel, who's holding the infection device, red.
"I'm infected." You and Joel say simultaneously.
