Decided to see what happens if you shoot fire and dynamite arrows at the widow's house while she is sitting on the porch in the epilogue. For some reason, she flees inside....INSIDE a house that is ON FIRE. Even locks the door.
Obviously, I had to attempt to see if she was okay and if so, rescue her. She didn't like that. They never expect you to be able to clip through walls. Poor NPCs don't know what to do when that happens.
