The Puppetmaster

On their way to the invasion rondevu point, the gang stays with an elderly woman (who they later find out is also a native of the Southern Water Tribe) running a small "hotel" after she warns them that the woods in this town are not safe. After discovering people have been mysteriously going missing after going into the woods during a full moon the gang suspects the spirits may have a hand in it, however the truth shocks them. Meanwhile, the elderly woman teaches Katara a few waterbending techniques, one of which she does not approve of.
