That just doesn't leave us any choice but to have an Impromptu Challenge.  These usually turn out one or two entries, so it's totally worthwhile to offer a prompt for any willing writers.
I will also encourage those who usually just read (possibly even lurk in the background ;), to make a statement concerning the prompt.  Just a thought or observation.  You never know when what you see will help a writer to spin out a story.
So, let's journey into something we visited two years ago.  Solve the mystery and help Illya save his partner.
