Relationship between Grog and Percy

Ordinarily, Percy and Grog don't really interact very much, save for the occasional small conversation here and there. Grog acknowledges that Percy is an intellectual, and in turn Percy typically finds Grog charming after a fashion.

Episode 40 however; involved Grog and Percy arguing about what to do with a githyhanki skull with a jewel embedded in an eye socket. Inside the jewel was a creature that promised to grant a wish if it could be released. Because Percy and Grog wanted radically different things, the two of them nearly came to blows.

Still, they both value what the other brings to battle and save for that isolated event the two of them are cordial with one another.
