Skyland Season 2 Episode 4 Cortes' Secret

Cortes' brother Christophe arrives at Puerto Angel with a problem, his ship the Callisto is trapped in an ice block and he needs to free it. Having been betrayed by his brother in the past, Cortes is wary of helping him, but has no choice because the Calllisto is an exact replica of the St. Nazaire, which would be dangerous should it fall into Sphere hands. The Sphere knows of the Callisto's location and soon the rebels find themselves engaged in a fierce battle. Christophe seizes the opportunity to save the day and in doing so sacrifices his ship, leaving Cortes to finally see his brother in a new light.
