I would recommend 'Rhys and Vaughn's Adventure'. It's full of exciting plot twists and the way it portrays their bond is really interesting. It shows how they support each other through various challenges.
You can also try Fanfiction.net. It's been around for a long time and has a lot of user - generated content. Look for the Harvest Moon section and then specifically for stories involving Vaughn and Chelsea. However, the quality can vary, so you might need to skim through a few to find the good ones.
Another option is to check out Tumblr. There are often fanfic writers who post snippets or links to their full works on their blogs. You can search for relevant tags like #rhysxhandsomejackfanfic or #borderlandsfanfic. Some Discord servers dedicated to Borderlands may also have channels where fans share their fanfics. You just need to join the right server and look around.

In Rhys x Handsome Jack fanfiction, the relationship can be seen as a study in contrasts. Rhys represents the everyman trying to make his way in a chaotic world, while Handsome Jack is the larger - than - life figure. Some fanfictions might focus on how Rhys could potentially change Jack, or vice versa. For example, Rhys's sense of morality could rub off on Jack, or Jack's confidence could inspire Rhys to be more assertive. It's also interesting to see how their different goals, Rhys's perhaps more altruistic and Jack's self - serving, clash or converge within the stories.
One great Vaughn x Chelsea fanfiction is 'The Unlikely Bond'. It beautifully explores the relationship between Vaughn and Chelsea in a unique setting. The characters are well - developed, and the story has an engaging plot that keeps you hooked from start to finish.
Your best bet would be to search on large fanfic platforms. Archive of Our Own (AO3) is a great place to start. Just go to the website, type in 'Castle' in the search bar, and then add keywords like 'Vaughn', 'Beckett', and'seeing a kiss'. Another option is Fanfiction.net. Navigate to the 'Castle' section and use the same kind of keyword search. There may also be some smaller, more specialized fanfic sites related to the show, but AO3 and Fanfiction.net usually have a wide range of content.
A popular theme is the 'enemies - to - friends' or 'enemies - to - lovers' arc. Given their initial antagonistic relationship in the original source material, it's fascinating to see how fanfiction writers transform it. Another theme is power struggle. Since Handsome Jack is a powerful figure and Rhys is often in a position of relative weakness, the exploration of how they negotiate power between them is common.
Friendship is a common theme. Many fanfictions show how August and Vaughn start as friends and then their relationship deepens into something more. For example, in some stories, they support each other through difficult times at school or in their personal lives, which forms a strong bond between them.
