Good, Angie did a smart thing, but I think you shouldn’t write,

“The Next Day…” in such plain text. Something more like, “The following day, Seth walked into the house…” and not make it seems like some bold heading.

And separating the dialogue and such maybe be a good idea since I assume you have characters left, and it’d be an easier read.

Nice back and forth giving little hints about who each character is. I was getting the impression she was the settler and he was the reacher all along.

Nice last line, but I’d like to know the back story. She could be just a brainless lemming.
