Grimm paints a canvas with his own blood he's like the Mad Artist

A villain/criminal tries to steal a girls mask in the season 2 but his fingers get sliced off and puffy brown stuff starts to come out of them and another man shoots them off.

They use d***, hell few uses of s***, d*** it and hell are the major one's.

Grimm has a hallway of painting made of blood some might think it's intense because of the music
