Before I sold my first song, I was in the studio all day. Waitering and bartending all night. There's no short-cuts, unless you're a prodigy.

Oscar and Archie's meeting

Through his connection with Valerie Brown, Oscar met up with aspiring musician, and Riverdale local, Archie Andrews. He interviewed Archie, hoping to get a better perspective on what he hopes to accomplish. He explained to Archie that there's no room for anything else in his life, like football, he would have to put all his time and dedication into. Oscar's job isn't to teach performers, he teaches songwriting, by focusing on craft, composition and lyrics. If the two of them are to have any kind of relation in the near future, they'll first need an understanding of how things work.

During their next meeting, he was not impressed by Archie's skills, Oscar referred to his music as juvenile and repetitive, each one was a break-up song. Unfortunately for Archie, Oscar can not help him, as the connection is not there. He doesn't believe he can reach Archie, the same way his former music teacher did. [2]
