Now, you'll head to your messages with the MESSENGER, going back to the beginning for both your KEY and your LOCK. At the start of the messages, you'll see the first word as your KEY, as it appears there with no further capitalization or appending. Your LOCK can be seen similarly, but you've known what it'd be from the start—it's the season most sacred to you, that accompanies the day that first message was sent, all in lowercase.
