Re: MCU Phase 3: Have it your way
SHIELD doesn't have to have a big presence to fulfill the narrator role, just show up to create the illusion to the audience they were watching and are aware.
The map at the end of IM2 is what I am talking about. There are flash points in places that we have not gone to yet. Stuff like that shows SHIELD has their act together. SHIELD knows more than the audience and we are begging them to reveal what they know.
