Agreed. Pretty sure everyone had been suspecting an ocean/mermaid-themed seasons for years, and Season 5 delivered.

Season 4's ending to me just seemed so "closed" that I was always wondering if they wanted to end there, but they must've had Season 5 planned already seeing as production is a year ahead.

It's interesting to see.
