I can totally see the resemblance

It's definitely good to see existing members of the SHIELD organization incorporated into the show, particularly ones as interesting as this one. Hand, Sitwell, Hill, etc. are just names to me so far, so it'll be good to see one stand out. Plus, it'll be a fun ride.
Any casting news for the other addition? Are there any African American SHIELD agents not currently played by Sam Jackson who could be added?
My personal guess: AIM reorganized. Under whose leadership?
I think it's AIM, but I've made the argument that it's Quinn (or at least associated with Quinn in some way). Either way, it's hard to find any existing Marvel character that fits well with the Clairvoyant. Part of my thought process is that it's someone who isn't actually Clairvoyant, but that's seeming harder and harder to believe. I could see MODOK as a sort of Total Information Awareness/PRISM type system that takes all information available on the internet and uses it to reach its conclusions. Would fit well with the themes introduced with SHIELD secrecy and Skye.
