Seto POV
It had been a week since the brothers had gone to the convention. Since then, Seto had asked Serenity out (and been accepted), made 2 more costumes (Eiri Yuki from Gravitation and Tsume from Wolf's rain), discovered that Yugi would have kept it a secret (but only because he would never tell anyone that he had gone to the convention) and told the world that he would be leaving Kaiba Corp (and handing leadership over to his little brother). Who would have thought that Mokuba loving Gravitation would cause all that to happen. When it came down to it, it would have been better if they had been able to talk about their secrets before being caught out. Well, they know for next time.
Mokuba POV
It had been a week since the Kaiba's had caught each other out at the anime convention. Since that day, Mokuba had made one more cosplay (Momiji from Fruits basket and started a second (Ryuichi from Gravitation), Got his hair cut neatly (since he had only done a ruff job), discovered that Serenity had been in love with Seto since their ride on the blimp (and told Seto straight away), Taken over Kaiba Corp (but only because his brother asked him to) and been kidnapped (but it was really just Yugi making sure Mokuba didn't tell anyone about being seen at the con). All this because of his love for cosplaying and Gravitation. Maybe next time, he and his Nii-sama will be able to talk about their secrets. Well he knows for next time, and so does his brother.
