One common theme is redemption. Ketch has done some not - so - great things in the show, and in fanfiction, he often gets a chance to redeem himself. For example, he might help the Winchesters in a big way to make up for his past actions.
Since we only know the title 'the real megan is missing story', it's difficult to say exactly who Megan is. She might be a young girl from a small town, or a woman living in a big city. Maybe she has a family, friends, and a job that are all affected by her disappearance.
There's not enough information to know exactly who Megan is in'megan is mossing real story'. It could be a common name for a fictional character in a story that is being developed, or perhaps it's a real person that the speaker is familiar with but hasn't provided enough context for others to identify. For example, it could be a Megan from a school project where a real story was expected but is missing.
One plot idea could be Ketch getting involved in a time - travel adventure within the Supernatural universe. He could go back in time and interact with the Winchester brothers at different points in their lives, changing the course of events in unexpected ways.
You can try websites like Archive of Our Own (AO3). It has a vast collection of fanfictions including those related to Supernatural. Just search for 'Supernatural' in the search bar and then look for stories that might mention 'ketch' in the summary or tags.
One popular Arthur Ketch and Dean fanfic is 'The Unlikely Alliance'. It delves into their complex relationship as they are forced to work together on a hunt. Another great one could be 'Ketch's Redemption', which shows Ketch's journey towards redemption in Dean's eyes. And there's also 'Dean and Ketch: A New Understanding' that focuses on how they gradually come to respect each other.
The fact that Arthur Ketch and Dean are from different backgrounds within the same universe is a big draw. Ketch has his own set of values and methods that are often in contrast to Dean's. Fanfics allow us to explore how these differences play out. Additionally, the chemistry between them, whether it's a tense, confrontational chemistry or a more collaborative one as the story progresses, is exciting to read. There's also the idea of redemption in some of the fanfics. If Ketch has done wrong in the past, seeing how Dean might be involved in his journey towards redemption or how they both grow from their past mistakes is really appealing to readers.
Another option is to join Supernatural fan groups on social media platforms like Facebook or Reddit. Fans often share their favorite fanfictions in these groups. You can ask specifically for Ketch fanfictions, and someone might be able to point you in the right direction.
I'm not sure exactly who Megan is without watching the story in detail. But she's likely a person who has a very high weight and is on a journey to change her life in the context of 'my 600 lb life'.
It's hard to say for sure. It depends on how it was written and presented. Maybe the author drew inspiration from real life but changed some details for the sake of the story.
