Is the "shore-side restaurant" important?
Hmm. How to deal with the two soup problem.
Did the person he ate with make the soup with the human in it?
Did the person he ate with make the other soup?
Did the person who shot himself make the soup with a kid/spouse in it?
Did the person who shot himself make the other soup?
Was the soup with the kid/spouse in it made at the restaurant?
Was the other soup made at the restaurant?
