Just caught up to The Killing.

4. My opinion...Richmond dated from a call-out service some time or another...

but, whether he knew it as Beau Soleil or just as dates arranged for him remains to be discovered by the viewers.
Jaime seems genuinely surprised at the decadence of Tom Drexler's private home but that doesn't mean Jaime
didn't arrange dates for Richmond through the website or by phone.
Richmond was always talking about the Orpheus tale to anyone who would listen. Wouldn't be hard for anyone to
decide to use that name in connection with Richmond.

AMC has a great site on The Killing page: blog and talk...where you can go to
the talk forum and learn a lot of other ideas about the show.
