@Dezaki I didn't forget. Kidnapping Iska was
not a royal order, Rin acted
alone. Alice is the
direct superior of Rin, and thus responsible for her personal actions. She
also goes along with the kidnapping, like you mentioned. Alice is
equally guilty, if not
more.
Rin is more of a footsoldier, while Alice is a commander. Rin broke the ceasefire, commiting a warcrime in the process,
with permission from Alice.
