Play Pepin's quest intro dialog if the player skips the intro

If the player discovers and enters the poison water set level before talking to Pepin the poison water quest does not appear in the quest log and his first set of dialog doesn't play. Handle this case specifically to ensure the player gets the message and can see progress.
