My favorite ep of Sorcerer Hunters is definitely episode 5 "A Dreamy Girl at Lakeside." That adventure was not in the manga, but it's easily my favorite Sorcerer Hunters adventure. Probably because it sweetly highlighted the trait I find most admirable in Carrot. (And, no, it's not his impeccable taste in women or his fearless perseverance.)
Kinda interesting how in some movies and TV shows, some of the cooler moments are the ones not in the books. Like in Godfather, the "leave the gun, don't forget the cannolis" scene is iconic and awesome, but was never in the book. My favorite scene in the Game of Thrones show was when Jon Snow and Sam Tarly were talking about girls and how Jon didn't want to get a girl pregnant and make another bastard and Sam says, "So... you didn't know where to put it!" Not in the book, but a great scene.
