Grimm - S1E8 - Game Ogre

After three murders in this episode, Hank realizes that the victims are all connected to the arrest and conviction of Oleg Stark, who's since escaped and is tracking down those who sentenced him.  In researching his file, Nick discovers that Stark "displays signs of congenital analgesia, a rare genetic disorder which deadens the nerve endings, making it difficult to process pain" and has "abnormally dense" bones:

Later Nick discovers that Stark is a Siegbarste, which Monroe describes as "your basic ogre."

It's significant that his last name is Stark - the German word for strong.  Stark's deadened nerve endings and dense bones seem to contribute to his strength.  At the very least, they help to increase his persistence.

I think it's also significant that that characteristic is his last name.  It's sort of the opposite of the word Grimm.  In the show, it seems that the Grimm Brothers' last name has become the appellation of those who can see Wesen.

Grimm - S3E21 - The Inheritance

This post contains some minor spoilers.

After re-watching this episode of Grimm, I started thinking about the name of one of the characters - Rolek Porter.  It's not a very common name, so I thought that there had to be some sort of reference hidden in it.  I couldn't come up with anything for Rolek, but the Porter part is actually pretty descriptive of the character.

Rolek Porter is dying, and before he's gone, he wants to give Nick a trunk of some Grimm-related things and an-other key.  Like Nick, Porter is a Grimm, but he doesn't seem to be as involved in the Wesen world as Nick is.  Porter tells Nick that he (Porter) "couldn't do what [his ancestors] did" or what Nick does.  So while Porter has a trunk of Grimm things, he doesn't really use them himself (and his son isn't a Grimm so he wouldn't have a use for them).  This is where the Porter part of his name comes in; he just carries the stuff.

That section of his name works especially well in that Porter came from Pennsylvania to Oregon to give Nick the trunk.  It's also interesting that Porter is first introduced in a hotel, so there's a tenuous connection to hotel porters:

Grimm - S3E15 - Once We Were Gods

Episode fifteen of season three of Grimm starts with some construction workers finding an Egyptian sarcophagus in a secret room:

They call a professor named Vera Gates to investigate it:

It occurred to me how appropriate the name Vera Gates is for a scientist.

I'm fairly certain that Vera comes from the Latin word verum, which means truth.  It's the same root that the word veracity comes from (also the word very, which I found interesting).  So truth combined with gates seems to name a character who is a guardian of knowledge.  It's especially apt considering her dedication to her job, which doesn't falter even after her lab has been broken into and vandalized.  She asserts, "This is science.  I won't be scared into not doing my research."

Grimm - S3E11 - The Good Soldier

This post contains spoilers.

I've been re-watching season three of Grimm, and I noticed a small but significant detail in episode eleven - "The Good Soldier."

After a murder, Nick and Hank investigate Jim McCabe, a coworker of the murder victim.  They visit him at his office, where he has a statue of a lion on his desk:

After two similar murders, Nick and Hank discover that the murderer they're looking for is a manticore.  (Unbeknownst to them, there are actually two murderers.)  In the trailer, they - along with Juliette - learn that the manticore has the body of a lion (or a Lowen, in the Grimm terminology) with the tail of a scorpion:

The lion statue on his desk appears innocuous early in the episode, but it seems to function as a sort of fore-shadowing that McCabe, who committed two of the murders, is a manticore:

The episode's plot mostly revolves around Frankie Gonzales, an army specialist who was raped.  (Her colonel kills one of her rapists as a sort of vengeance, and McCabe kills an-other of her rapists and his wife in order to prevent a confession that would reveal him as a third rapist.)  Gonzales carves the date of her attack (November 11, 2010) into her arm, and - in one instance - blots the wound with a napkin so that the date transfers in her blood:

She then gives this to one of her rapists in an attempt to get him to confess.

I think the date is significant.  November 11 is Veterans Day, so it has a connection to the military.  It's also the date of the Armistice in World War I (which Veteran's Day came out of), but in the episode, it marks the opposite, as it's the beginning of all the problems.
