Patch 8.2.2863 (after 8.2.2862)

ZOOT:  I'm afraid our life must seem very dull and quiet compared to yours.
       We are but eightscore young blondes, all between sixteen and
       nineteen-and-a-half, cut off in this castle, with no one to protect us.
       Oooh.  It is a lonely life ... bathing ...  dressing ... undressing ...
       making exciting underwear....
