Red Dead Redemption 2: 10 Mind-Blowing Details You Totally Missed

Rockstar loves to sneak in small references to their previous titles and Red Dead features not one but two potential links to the Epsilon program, a feature of the Grand Theft Auto series.

The program, run by Cris (with no H) Formage, is essentially the GTA writers poking fun at cult-like followings such as Scientology. One key figure in the program's belief, known as Kaff, is an unidentified individual that features a prominent birthmark on the right side of their face.

Red Dead players may immediately think of the time traveler, Francis Sinclair, from the Geology for Beginners stranger mission who shares a similar mark. Not to mention Sinclair also dresses in similar blue apparel to members of the Epsilon Program.

However, thanks to data-miners we now have access to another character model that shares the same marking. The mysterious Princess Isabeau Katharina Zinsmeister also has the same birthmark. While the birthmark is not visible on her younger portrait, her adult model proves not only is she alive but could be this Kaff figure in question.
