My favorite episode is season 2 episode 25 "Sea Change". I just love leo (cleo&lewis) my favorite couple used to be rikki and zane but now i think i lyke leo better. But sea change is my favorite because lewis breaks up w/ charlotte (haha in your face evil mermaid! lol) and he gets back w/ cleo and i thought it was soo sweet of Lewis to come and save her. Leo 4ever!!!
