But that wouldn't make any sense. Claire is shown in the Hero's Forge and she first visits Trollmarket in "Return of the Trollhunter". I would've thought it takes place between "Return of the Trollhunter" and "Mudslinging"?
More specifically, according to the tweet, Richard Hamilton said that it's set before Angor Rot's appearance in Return of the Trollhunter. I think he and Marc may have been a little confused when thinking of it in terms of between episode 13 and 14, that's why I kinda editted that part. Or he just misspoke with the episode numbers.
