I think Zephos is one of many, for lack of a better word, "messy" cases in The Wind Waker. He shows up once, talks to you for a bit, tricks you into loving him, then never appears again. He's the effin' wind god. In a game where wind's in the title, he deserves more than a five-minute pointless appearance.
Ah, well, it's a kick in the pants...
