I don't want to get lost in there, so I'll head back to the guys, and change back once I'm far enough away from the barn that I'm not worried about being seen.
To the group: you see a rat approach, that pauses when it's a bit away from you. Then, it starts to grow, and turns back into Elizabeth. She walks up to you.
"The thing is in the barn. It's huge, and it's too dark to make much out in the way of details. They way it's breathing makes it sound injured, but I don't know that we can just shoot it to death; at least, not with just the three of us. There's a thick trail of some sort of slime leading into the barn. I'm not sure how long this thing is going to stay here.
I went to the house. It's dark, but it smells like spoiled food, blood, and gunpowder. My guess is, the homeowners shot at this thing and got killed, but I can't really tell without any more light, and I don't dare light the place up with that... thing so close by."
Bhu, how far is this farm from the town?
