[Emmy's expression darkens considerably - she was angry before, of course, but now that she's back here with all her prior knowledge....it's a different kind of anger, fueled more by pure disappointment than righteousness.] 

He...he manipulated the Professor's best friend from childhood, a man he thought was dead, into doing these terrible things, into hating all his previous friends, just for his selfish goals. I mean, I know I can't really speak considering I'm also being...manipulative, but I'd never hurt anyone! 

[Well. Mooks and other assorted nasties don't count, of course.] 

And I'd certainly n-never try to kill anyone, it's just....it's just plain wrong! He's so selfish! If he was here, I'd....I'd... 

[Obviously unsure about just what she'd do, Emmy simply throws her hands up in the air and lets out a cry of frustration.] 

He was so kind to me, Mr Kimblee! He...he asked me to....and I said yes... 

[The sudden explosion of blushing should hopefully work to fill in just what Descole had asked, as Emmy declines to elaborate.] 

...and now everything is ruined.
