Am I glad to see you!
I'm a little banged-up, but I can still get around.
Sure thing! And, hey, seeing as you're the first person I've seen in a while... can I tell you something?
A friend of mine from the survivor camp, Tammy... we got separated when a bunch of... those things chased us.
Right...well, she was headed for that diner not far from here... could you see see if she's okay?
