Marcus Flint was a sly, conniving moron. Katie Bell abused him with her fellow team mates as it became clear he had purposely made the Gryffindors lose their practice time on the pitch. The argument between Oliver and him turned noticeable when Oliver Wood lost it and launched himself on the Slytherin captain.

Noticeable enough for Professor Snape, who interfered and took away thirty points from the Gryffindor house. Wise for the moment, the Weasley twins pulled Oliver off Marcus just in time before Slytherin enjoyed the satisfaction of Gryffindor losing more points.

Oliver hissed: “Wait till the match, Marcus!”
