Who is James Morland from Northanger Abbey and what is their importance?

James Morland is the oldest of the numerous Morland siblings and is probably in his early twenties during the time considered in the novel. Like Catherine, James is a poor judge of character and believes the buffoonery of John Thorpe to signal real friendship and the coquettish behavior of Isabella Thorpe to signify real devotion and love. James has been away at school for perhaps a year before the opening of the novel; at school he has befriended John.
