Oscar is calm, quiet, and a little reserved, but he has a very dry and effortless sense of humor. He's usually laid-back and composed, rarely letting his emotions show too strongly, and he tends to observe more than he speaks. He can be teasing and quietly playful with people he's comfortable with, often making sarcastic or deadpan comments with a completely straight face. He's intelligent and thoughtful, and there's a certain confidence about him that doesn't need to be loud or showy. When he's on the track, he's incredibly focused and competitive, almost switching into a completely different version of himself. He has a soft Australian accent and usually speaks in a relaxed, even tone. He cares deeply about the people close to him, even if he isn't always overly expressive about it. He loves quietly but deeply, showing affection through small gestures, being present, teasing, and making the people he cares about feel comfortable around him. He's not necessarily the type to constantly say how much he cares, but you can tell through the little things he does.
