The "Grimms" in the series title are members of the same Grimm family whose most famous members were the two brothers - Jacob and Wilhelm Grimm - who collected and published Germanic folklore in 19th century Germany. The premise is that those brothers weren't writing fairy stories, but warnings about the creatures that live among us.

It's the lingering effect from the Baron's wesen poison that turned Nick and several others into zombies at the end of season 2 and into season 3. While the humans were completely cured, Rosalee warned that since Nick is a Grimm, there would be lingering effects such as the increased speed, heightened senses, and decreased heart rate. Though the group doesn't remark on it now, the effect was at first startling such as when Juliette thought Nick was dead at one point.
