In this episode, Kaylee decides to imitate her brother by going spelunking, which eventually leads to another heart-stopping lesson of sexual education for little sister (who's becoming quite a horny little cum addict by this... time) and another startling accidental discovery which our hero shares with both DIane at the library and Madalyn at the church. While the reaction of the latter is somewhat scary (but sexy), Diane is quick enough to understand that the fabled treasure of the Tikpak might be much closer at hand than anticipated - and after a long and humiliating effort to get himself licensed for using a kayak across the river, Alex is finally able to join Diane on her quest to prove that the Tikpak did actually land at Cape Vedra, after all.
