Resting her chin on her knees, Susan was attempting to figure out a solution for him, or at least some encouraging words. "Nothing is more distressing then a guilty conscious, Ernie. I think that if you can't find evidence of them, maybe it's time to drop the attempts to find the suspect, and wait for the suspect, or suspects to come forward." It sounded so simple, but maybe Susan was on to something.
"Or, perhaps pin the blame on someone else, someone you know is truly innocent, perhaps then the real perpetrator or perpetrators, will come forward. If it is Ginny and Sam, knowing them, they wouldn't let someone else fall for something they didn't do, right? After all, they're not in Slytherin." Susan hoped that made sense, and hopefully he wouldn't think any less of her for thinking up something so devious, and sly. She wasn't exactly the most deceptive of people, but desperate times, yeah?
