Final answer:
In F. Scott Fitzgerald's novel 'The Great Gatsby', the character Gatsby becomes aggressive towards someone after feeling secure in his relationship with Daisy.
Step-by-step explanation:
The subject of this question is English. The question is asking about a character in a literary work who becomes aggressive towards someone else after feeling secure in a relationship. In this case, the character Gatsby, from F. Scott Fitzgerald's novel 'The Great Gatsby', is taunting someone saying 'I know your wife.' This demonstrates Gatsby's change in behavior after feeling confident in his relationship with Daisy.
Tom Buchanan is the main antagonist in The Great Gatsby . An aggressive and physically imposing man, Tom represents the biggest obstacle standing between Gatsby and Daisy's reunion.
There is a great deal of glamour and party-going in The Great Gatsby, but there is also a considerable amount of violence. Myrtle Wilson, a woman who is said to have 'tremendous vitality' (p. 131), has had her nose broken by Tom Buchanan, and now she is killed by a car driven by Daisy.
