I liked this one.

For some reason, when I read about different people seeing the same alien faced man I thought of the movie "Signs"...however, the twist with him instead being an "advanced", futuristic man was a nice one.

And Marshall's ending with how the man would ask how his arm was healed was quite poignant. My heart sunk along with the husband's as the future man was telling him what he was going to find at his house after his wife took the "medicine".
