"Quill" received positive reviews. The A.V. Club's Kevin McFarland gave the episode a "B" grade and wrote, "If last week's episode — with a case centered around child kidnapping, inbreeding and ritualistic rape — was what Grimm: SVU would look like, now we know what this show would look like when filtered through a minor zombie plague outbreak. 'Quill' isn't Grimm's version of 28 Days Later or Dawn of the Dead or anything apocalyptic, it’s a standard plague, spreading through a small population, eventually infecting one of the major characters, before a quick remedy comes through right before the episode ends. Nothing particularly special on the plot front, but that's not as important as the character progress, which is moving along nicely to build a stronger character base so that riskier episodic plots will have a better chance for success."[3]

Nick McHatton from TV Fanatic, gave a 4.5 star rating out of 5, stating: "If there's one thing Grimm does well, it's making unlikable characters actually likable (remember my disdain for Juliette?), and 'Quill' accomplishes just that with Hank. Congratulations on joining the pack. Hank! You're official off the 'I don't care about you' list!"[4]

Shilo Adams from TV Overmind, wrote: "Grimm has done a fine job of filling out the Wesen world. Be it through the introduction of different types of creatures, a look at the ways they go about their intra-species hierarchy. Don’t get me wrong, the show is quite fantastical and appropriately supernatural; it's just that, nearly 30 episodes into its run, Grimm has managed to underline its theme (human duality) fairly well while making the Wesen world feel like, well, a world."[5]

Josie Campbell from TV.com wrote, "Thematically Grimm continues to upend the pieces on the board. Just like Hank and Juliette, we're all frantically evaluating and re-evaluating with every new piece of information we have. We also have to ask ourselves what good and bad means to the various agendas and plots flying around. In Season 1 it would have been a good thing for Juliette to find out about Nick being a Grimm. Now that she has no memory of him, this feels like it'll lead to disaster."[6]
