Shin's summons to the castle doesn't go exactly as he thought it would when the princess challenges him to a duel. Then when the aftermath of their fight goes horribly awry, it's up to Schnee to investigate. 
But that's all in the past now.
.لكنّ ذلك في الماضي الآن
Doch das hat jetzt ein Ende.
Pero eso es parte del pasado.
Pero lo pasado, pasado está.
Cela dit, cette époque est révolue.
Ma questo è un capitolo ormai chiuso...
Mas isso tudo está no passado agora.
Но теперь это в прошлом.
