you were currently running from walkers while being injured, you ran inside an empty classroom and hid so you wouldn't be found, after a few minutes the noise of the walkers stopped so you quickly got out of your hiding spot but couldn't do alot since you were still injured, you stayed in the classroom until another person came in holding a gun and pointed it at you.

"who are you and did you get bit." he said in a serious tone keeping the gun pointed at you
