He's very openly affectionate to people he's close with and can easily fall into obsession and idealization over his favourite people - namely his brother and fiancée. He isn't ever possessive or easily jealous over them and is just happy to make them happy. This can lend to him being pretty servile when it comes to them both.
More open to talking to people and making friends than his brother, but only if he finds them interesting enough - and he has a high bar for it. Generally is more friendly to everyone even if he actively doesn't like the person.
Very interested in the makeup and practical effects side of film. Often practices in his free time.
