He is an OC that I created for my story 'Sly Cooper's Adventures in the Seventeenth Centuries' on Fanfiction.net. My story takes place after 'Thieves in Time' and it explores the possibility that Sly is in Egypt but is in the year 1615. Ron is a sailor onboard the 'Ocean's Mistress'. He is very easy going and loves his booze. He befriends Sly in my story.
I've start reading your fanfic and I had to say that make it as a minisequel for the next game if they are able to one day....pry for Sly 5!
Ermagerd! There HAS to be a Sly 5! If they leave the Sly series as it is and stops, I will explode! the least they can do is give the series an ending that is satisfying. But for now, I'm stuff with Fanfiction.
