Kamille and Fa take Shinta and Qum down to an Alpine-themed space colony for a vacation and meet a strange woman named Rosamia, who is convinced that she is Kamille's kid sister. Kamille plays along, much to Fa's chagrin, in an attempt to figure out more about her. Meanwhile, Haman Karn has taken Mineva Zabi on an outing to the same colony. Mineva gets to interact with kids her own age - Shinta and Qum - for the first time, and it delights her. Some rogue Zeons start a skirmish with Quattro inside the colony, which is damaged, forcing everyone to take shelter. Ultimately, Rosamia (or "Rosammy") is brought back to the Argama with Kamille's group, and Emma freaks her out.
