There’s a sea battle and ultimately Mu and Kira win.
But my favorite part is when Kira and Cagalli hug. The crew is allowed to take breaks on deck to enjoy the sunshine and the ocean. Kira comes out on deck and he’s feeling pretty down. Cagalli comes out and hugs him saying, “I can’t ignore a child who’s been crying!”
And then they talk about Coordinators in general and his complex situation. Even though they haven’t known each other that long, Cagalli is being a fabulous friend.
