User blog comment:ChishioKunrin/Grimm are attracted to negativity, huh?/@comment-25436196-20141010030833

I was reading Matt the Mammoth Rider's recap of chapter 9 earlier today, and aside from the Nevermore, he raised the exact same points. Pretty interesting stuff. He also pointed out that while Oobleck was interrogating the team, Ruby was the only one who wasn't surrounded by dead Grimm, and how the Grimm apparently not attacking her could symbolize how she's the only one who has no doubts on her mind. It's just so freakin' philosophical, man...

I don't if Monty already had the negativity concept in mind when he made the trailer, or if Miles and Kerry were thinking about it when they wrote the other scenes (though I like to think they did), but it sure is nice to think about it. The idea that all of these incidents were connected by a common factor that was only revealed later on can add a lot of depth to the scenes
