Red Dead Redemption 2 unfortunately doesn't have a partner system where you can just hang out with your favorite member of the Van der Linde gang, but a newly discovered workaround found a way where that's possible. So long as your favorite member of the Van der Linde gang is Charles.
In Red Dead Redemption 2 the only real time you play alongside your crew is in story missions and quests. The open world portions are largely a solo affair. However, at the end of Chapter 2 you'll find yourself with Charles and it turns out if you don't follow-through with the chapter's final objective, you and Charles can just hang out and explore the open world together.
Players wondered if forcing Charles out of the mission loop and into the open world would cause him to keep talking about the object like Navi in Ocarina of Time, but according to players Charles is "actually pretty quiet about it, just happy to be along."
Apparently, Charles will even "throw down against any strangers" and the only time his actions are impeded are when you're Wanted. Basically, your Arthur Morgan and Charles can just go about the Wild West as a duo.
Unfortunately this isn't something that can just be done at any time and it kind of sucks that you can't have a partner with you during a mission. Maybe Rockstar is saving the feature for Red Dead Online?
