Oooooooo, good question.

I do like the character developement of Sess becauce of Rin showing up.

And one of my absolute favorite scenes in Inu-Yasha is when Sesshomaru spots a danger, and tells Rin to Freeze. After a good portion of time goes by, Sess tells Rin 'you can move again' and she gleefully complies. That's _AfteR_ she remained motionless for so long, obeying to the letter what Sess said.

I love that type of loyalty/trust.

Will he turn on her?
Probably not directly....but if forced somehow socially....big question.
Perhaps not having any idea is better because we cannot predict what will happen, and thus read the story with more tension? (enjoyable tension, that is)
