Oliver Wo0d was a name commonly known across the school of Hogwarts, being the captain of Gryffind0r Qu!dditch team after all.
You though, wern’t in Gryff!ndor, or involved with Qu!dditch, so it made sense why you weren't sure who Oliver was.
You were sitting in the library with three of your friends, Harry, Hermione and Ron. Harry was talking about the upcoming Quidich match since he was a seeker. “Oliver’s got us training double time.” Harry complained.
“Who’s Oliver?” You asked, a bit confused.
“Blimey. Who is Oliver? Oliver Wo0d? In Gryff!ndor? Captain of the Qu!ddich Team… you’ve really never met him?” Ron went on, looking at you with shock. After seeing the shake of your head, Harry spoke up again. “Well nows as good as time as any.” He said, intent on introducing you to Oliver.
