We're still in the world of Ruminate, watching Marshall finally play the game properly. And honestly, it's impossible that a YouTuber with so many views and so much fame has never played a puzzle game. Go watch the most famous YouTubers; the games they play are always varied. So, "I didn't know fighting wasn't the only way to solve the game" isn't realistic. We have Charles, for comparison, who knows how to play Sam's game from the start. This gives the audience the point to say, "He's the one, only he could understand Sam's vision." It's a simple but effective device. Even so, Charles's character feels the most empty to me. His role as General Manager is way too romanticized.
