11x12 Return Of Thunder, Part III

Blake is much more eager to save his brother than the Wind Rangers are, but they help anyway especially when they realize that the island is sinking. They find Hunter who struggles to find himself in his rage, forcing Blake to take matters into his own hands. Cam discovers where the Rangers are and contacts them; the Rangers find that there's only one way to make it off the island, but it's very risky. The Wind and Thunder Rangers have to work together but they're running out of time!
