Jon is observant, a trait he developed on account of being a bastard. Due to having been raised in a castle and trained by a master-at-arms, Jon is seen by some lower-born members of the Night's Watch as arrogant at first, though this changes when they become more friendly towards one another, as Jon is reminded of his nonetheless privileged background and decides to pass on his knowledge to them.
Jon looks solemn and guarded, and is considered sullen and quick to sense a slight.
Out of all the Stark children, Arya Stark is said to resemble Jon the most, as Robb, Sansa, Bran and Rickon take after their Tully mother, Catelyn. Because he looks so much like a Stark, Tyrion Lannister notes that whoever Jon's mother was, she left little of herself in her son's appearance. Jon resembles his father, Lord Eddard Stark. Jon has the long face of the Starks, with dark, brown hair and grey eyes so dark they almost seem black. He is graceful and quick, and has a lean build. Jon has more Stark-like features than any of his half-brothers. Appearance and Character See also: Images of Jon Snow
