Grimm is a big tom and despite his intimidating looks with the bones, he's incredibly respectful and rather tolerant. until someone gets rowdy or intolerant xD mostly it comes out when they ask about the bones. I had a small interaction played out OOCly with Grimm and Bonekeeper that helped me flesh him out a bit more. He doesn't have the ability to see/talk to the dead, but his brother's last wish was that Grimm would never leave him again (idr what exactly I wrote aside from his brother and him parting unexpectantly and this gets the brother in trouble and he gets mortally wounded and basically makes Grimm vow to never leave him alone again). he carries his brothers remains with him because of this. he cannot see/speak to his brother, so he speaks to the bones, and it allows him to keep him close. some cats might find that offensive, like the OOC with Bonekeeper, demanding that he bury the bones instead so his brother can rest. Grimm is adamant that his brother is at rest only so long as he is with him, and will fight tooth and claw with anyone who attempts to tell him otherwise. He would be equally as fiercly protective of anyone who worms their way into his heart, and finds wanton killing and violence abhorrent. he likely heard what happened with the clan cats recently and found it disdainful, so he's coming closer to the groups of cats to see what they are up to, and to help anyone out who doesn't want to be there any longer. (colonies would be lumped into this too)
