I can both interpret that as 'it was good' and as 'it was bad'. Care to elaborate?
Well as for the part I yelled at the screen at, that would be where Akiha "killed" Kohaku in the school, and regardless of the things Kohaku had done, I really didn't want her to die.
I ended up feeling the most sympathetic to Kohaku of all the characters so far *still haven't done Ciel yet* because of how she is. Her being like a doll and not being happy just made me wish more and more that she would have a happy ending to make up for everything, so when that part came around... I was upset, to say the least.
Well.. Thank god the real ending was adequately happy, although a little strange. I don't think it'd be that easy to make up with someone who tried to kill you >.>
And for Question's question *ha ha ha* I think we're to assume that in the Tohno routes Arcueid simply wasn't going after SHIKI. I thought we could assume that she didn't even awaken, but you do see her in one *Hisui's I think* route at one point, so she can't be. So I'm going with her just either not taking action or not being able to find him or something.
