Aang & Katara - meant to be, don't you agree
Right before the invasion, Aang kissed Katara. ::Sighs::
This kiss was in the episode Ember Island Players, Aang kissed Katara when she said "she was confused" - not the best kiss in the show.
When the war was over, Katara and Aang both shared a passionate kiss. ::Sighs::
They are cute together, arent they? xD
