Hello. I just re-watched the pilot episode, and I could be absolutely wrong, but I think there is Anteros (the Greek god of requited love) in it, when the title shows. Subtext? I can't help it, I'm 'clueing for looks' all over the show, because you spoiled me. :P I love your blog & metas btw, and I think you're brilliant! Also, sorry if that's already been answered.
A bit more context, per WIkipedia’s entry on Piccadilly Circus: :
You guys. Uh, yeah. This is true.
For reference, here’s Anteros, the Greek god of requited love… the wiki picture is this exact statue. That’s REQUITED love. REQUITED. Anteros is specifically the avenger of unrequited love.
SINCE THE PILOT. WHAT HAVE I BEEN SAYING? WHAT HAVE I BEEN SAYING?
Bless you, anon. Bless you.
While the statue is generally believed to depict Eros, it was created as an image of his twin brother, Anteros. The sculptor Alfred Gilbert had already sculpted a statue of Anteros and, when commissioned for the Shaftesbury Memorial Fountain, chose to reproduce the same subject, who, as “The God of Selfless Love” was deemed to represent the philanthropic 7th Earl of Shaftesbury suitably. Gilbert described Anteros as portraying “reflective and mature love, as opposed to Eros or Cupid, the frivolous tyrant.” The model for the sculpture was Gilbert’s studio assistant, a 16-year-old Italian, Angelo Colarossi (born 1875).
However, it should be mentioned that to a British audience this statue is instantly recognizable as one of the most famous symbols of London, and could simply have been intended as quick visual shorthand to tell the viewer where the story was about to unfold.
