User blog comment:Abelskie/The Grimm-ness of Nick/@comment-1966944-20120215075932

Although, it may not yet have been precisly explained by the writers, in watching the show I believe the creatures are extra sensitive to Nick's reaction when they let down their guard and reveal their "Creatureness"! As for a Grimmbeing able to control their "Grimness" we really don't know, since Nick is the only Grimm we've really seen in action for a extended period of time (Aunt Marie being the exception but she was killed off by the second episode) and Nick is still a Grimm in self-training. Learning the Grimm ropes so to speak. With that said, I don't know if a Grimm WANTS to control their Grimmness. Most of the creatures fear Grimms for a reason, based either on past personal experience or the experience of someone in their family, or by a bedtime story told to them as a little creature. So a Grimm's reputation precedes them, so it would be to their psychological advantage to let have a creature be aware of who they are! As for Charlotte, the "elderly" 26 year old Spinnetod, she was elderly, and had not practiced her "spider powers" for awhile so I would guess her "perceptions" were very weak or now non- existent! As for speculation, thats what makes a show like Grimm fun. It allows us to theorize on how things were, are, or going to be. Of course, its fun as long as the writers continue to give us clues and some answers within a timely manner!
