第 5 集: 學生們進行地面戰鬥與空戰訓練，Claire 和 Kal-El 則共度浪漫時光。

As time passes, the students get better at shooting and flying, but are soon taught in a grueling lesson by their instructors on how to do ground fighting. After an exhausting training, they enjoy their time by swimming and playing in a nearby lake. Claire and Kal-El separate from the group and share a romantic moment in the nearby forest. Later, Kal-El recalls his motives for joining the Isla group after being presented an offer from the government, knowing it is his chance to get revenge on Nina. Claire runs into him at school the next day, and is stunned by the similarity that Kal-El has with the former crown prince. She recalls her past: her family and community shunned her for her powers and tried to kill her, but she was able to obliterate the town. A priest from the Saint Aldista church was able to take her into control her powers, and she remembers the deaths of Karl's parents and his hatred towards her, and soon regrets her actions. Falling into a depression because of this, she is paid a visit by the island's navigator, Luis de Alarcon, and asked to join the island of Isla, and she accepts, changing her name to Claire. The students begin to learn how to dogfight, and it is clear that the tag team of Claire and Kal-El is far above the rest. On one practice run, they are shocked to see an invading force of planes, which are learned to be from Sky Clan, a once thought mythical nation that protected the Holy Spring. (Source: Wikipedia)
