Surely goes along the metaphor from Q's crumb:
>See attacks.
>The build is near complete.
>Growing exponentially.
>You are the frame.
>You are the support.
Huber's investigation began before (or was it right as?) Q hit the scene.. The foundation upon which all of this has all been built upon.
It's curious too- that the foundation hardly gets spoken of in the meta-building-sense. It's just kinda there, and the roof(top), and the walls/frame(US) are what keeps us safe.. but it's the foundation provides the bedrock for the entire new structure that has been under construction.
