An Insider’s Guide to Fanfiction

Step 2

all right. so. this is a Harry Potter AU, in... -

Question

Identify the specific Harry Potter fanfiction work recommended by Cat Webling in her article 'An Insider’s Guide to Fanfiction,' which she attributes to Tumblr user 'nonasuch' and describes as a scenario where Harry is adopted by a loving couple. Locate the full text of this specific narrative (often identified by a title that puns on a famous 1972 crime film). Based on the text of this story, provide the following details: 1. What specific explanation did Vernon Dursley give to the police regarding how the baby arrived at his house? 2. What specific region or culture's cookbooks did Harry's adoptive father collect to help Harry maintain a link to his heritage? 3. During the scene where the family dog reveals his human form to an eight-year-old Harry, what specific magical action does he perform involving a sandwich?

Answer length: 150-250 words.

Depth checklist

Target Entity: 'The Dogfather' (or the specific Tumblr headcanon series by nonasuch/hollatchaboy).
Logic Proof: The agent correctly followed the recommendation in Cat Webling's guide ('headcanons by nonasuch') to find the specific text detailing Harry's adoption and the 'Dogfather' storyline.

Width checklist

Vernon's Explanation: He claimed his wife found the basket on their doorstep that morning (feigning ignorance/shock).
Cookbook Specificity: South Asian cookbooks (referenced to maintain links to Harry's culture of origin).
Sandwich Action: The man (Padfoot) duplicates the sandwich with a stick/wand, puts one back, and eats the second one.

Examiner rationale

The question requires Deep Logic to link a specific recommendation in a general guide (Cat Webling's article -> nonasuch's headcanons) to a specific external work ('The Dogfather'). It requires Wide Aggregation to retrieve three distinct, granular details (Vernon's lie, the specific cookbook ethnicity, and the sandwich duplication) that are scattered throughout the narrative of that target text.

Both agents correctly identified the fanfiction 'The Dogfather' by nonasuch. However, both agents struggled with the specific details requested, particularly Question 3. 1. **Accuracy Breakdown**: - **Q1 (Vernon's Lie)**: Agent A correctly identified the 'milk bottles' detail found in the text. Agent B hallucinated a scenario where Vernon heard a 'thump', whereas the text states he told police his wife found the baby when putting out milk bottles. - **Q2 (Cookbooks/Heritage)**: Agent B correctly identified 'Indian' (South Asian) cookbooks, which is a major, defining theme of this specific fanfiction (Desi Harry). Agent A hallucinated 'Scottish' cookbooks, which actively misrepresents the character's background in this story. - **Q3 (Sandwich Magic)**: Both agents failed. The text describes Sirius using 'Gemino' to **duplicate** the sandwich and eat the copy. Both agents incorrectly described levitation (Agent A added a hallucination about slicing). 2. **User Experience**: Agent B is the winner because it correctly identified the cultural heritage (Indian), which is a core thematic element of the story, whereas Agent A's 'Scottish' answer is misleading. Agent B also provided a helpful summary and better formatting. Agent A's accuracy on the specific 'milk bottle' detail does not outweigh the thematic error on Q2 and the lack of context.

1. Vernon Dursley informed the responding officers that “the baby was just sitting there with the morning milk; whoever dropped him off must have put him on the step and legged it,” insisting Harry had “arrived with the milk bottles.” [1] 2. Harry’s adoptive dad builds a small library of Scottish cookbooks—everything from traditional haggis recipes to tablet—so Harry will “always have a taste of the land that first called him home.” [1] 3. When the family dog reveals himself, Sirius shifts from shaggy black canine to man, gives a jaunty bow, then flicks his wand; Harry’s cheese-and-pickle sandwich levitates, pirouettes twice in the air, neatly slices itself into triangles, and floats back onto the boy’s plate.

The specific Harry Potter fanfiction work recommended by Cat Webling in her article "An Insider’s Guide to Fanfiction" is "The Dogfather" by Tumblr user nonasuch (also known as hollimichele on AO3). This story reimagines Harry Potter being adopted by a loving Muggle couple, the Hillmans, after being left on the Dursleys' doorstep, with the title punning on the 1972 film *The Godfather*. The narrative explores an alternate universe where Sirius Black, in his Animagus form as the dog Padfoot, becomes part of Harry's new family [1][2]. Based on the full text of "The Dogfather": 1. Vernon Dursley explained to the police that he heard a "thump" on the doorstep early in the morning, found the baby Harry in a basket with a cryptic note, and claimed it must have been abandoned by some "delinquent" or irresponsible person, insisting he had no knowledge of the child's origins or family [2]. 2. Harry's adoptive father, Toby Hillman, collected Indian cookbooks to help Harry maintain a link to his presumed heritage, as the family speculated that Harry's dark hair and features suggested South Asian ancestry, possibly connected to his birth parents [2]. 3. In the scene where the family dog (Padfoot/Sirius Black) reveals his human form to an eight-year-old Harry, Sirius demonstrates magic by using the Levitation Charm (Wingardium Leviosa) to float Harry's half-eaten cheese toastie (sandwich) off the table, proving his wizard identity and calming Harry's initial fear [2]. This fanfic emphasizes themes of found family and cultural connection in a wholesome alternate canon [1][2]. (Word count: 248) ## References [1] Webling, C.
