Final Hint. This is it.
Thank goodness we have each other.
That guy startled me. I was starting to lose all focus after all these riddles, mysteries, and puzzles. If you ever find yourself staring out the window, trying to string together some clues and hints to make heads or tails of a puzzle, try this to take the sting out of the pain of defeat: sing a little tune, doesn’t matter what it is. It’s no sin to even whistle or hum the tune, what’s important is that the song is in your heart and in your mouth. I will be here waiting when you finally escape. I can’t wait for your report and the all-clear, so we can finally move in!
