Interestingly, Edward Ferrers is approximately the ONLY subject of chapters III and IV. First, we hear about him from the omniscient voice ("a gentlemanlike and pleasing young man") Second, the testimony (her thoughts) of Mrs. Dashwood ("he was quiet and unobtrusive, and she like him for it"), Third, the words of Marianne to her mother ("there is something wanting"). Fourth, the words of Marianne to Elinor ("no taste for drawing"). Fifth, the thoughts of Elinor ("There was, at times, a want of spirits about him").

Notice, the testimony gets more and more ominous.
