In the Hogwarts Novel:
Brett is starting his third year at St. Emrys University where he's reading (majoring in) Architecture at Fancourt College.
Brett is originally from North America, born in the US but raised in Canada. He attended a day school there while living with his grandmother. After she died, Brett transferred to Hogwarts where his older sister Australia was a student. Both Brett and his sister were in Gryffindor.
Australia is married to Yuri Gregorovitch. They live in Hogsmeade and have two dogs, Kiril the black lab and Vanya the chocolate lab. Australia is a Quidditch recruiter and Yuri is a coach for the Hogsmeade Humbatas. Brett lives in London in the flat where Yuri lived before marrying Australia.
Brett is waiting for Orei McCoi, currently in her 7th year, to graduate Hogwarts if she'll still have him by that time. Brett and Orei have an understanding that they may each look around and even go out with others. Brett thinks it's the only way for Orei as young as she is to be sure Brett's The One. Although Brett does have female friends, since leaving Hogwarts he's not gone on any real dates, prefering instead to go out strictly as friends and usually going out with a group.
