In Greek mythology Proteus is an early sea god, elusive, capable of constant change and assuming many forms. It is said he can foretell the future, something Carter and Finch pondered: “I don’t know what the future holds.” (Carter) “I wish I knew what that meant for the future.” (Finch)
The movie
Rashomon influenced Proteus, specifically in the opening of the episode when it is raining and the end when the clouds part and the sun shines; identical to the movie. Lighting is also used to great extent in this episode, particularly with the chilling but effective shot of Finch deducing that FBI Agent Fahey was, in fact, Declan; all while the lightning illuminates Declan’s menacing presence behind him.
If you want to know more about
Rashomon, hit Wikipedia. It sounds interesting, bound to keep one guessing as to what is real and what isn’t especially as it is told from the perspective of the individual, and each individual’s perspective is real to him or her but may not be reality; yeah, a bit of a mind bender.
Proteus was an homage to Greek mythological gods, Japanese films, a little bit of Batman (note the awning in the background as Finch and Reese leave the movie theater, it says “Gotham”) and a definitive nod to Agatha Christie. What I long ago learned is, pay attention to the little things that seem out of place, file them away, likely they’ll payoff in the end. That happened here as well. When Agent Fahey rebuffed Carter’s call, I wondered why and filed it away. I was right to.
