I just finished reading part 2, and I love it!

I love the evocative language, I could picture Tbilisi in perfect detail. I really enjoyed this part, especially this:
"She smiles back a little, mostly with her eyes, so he knows its real. Somehow, they understand each other, on a level he's not had before, not with anyone. It's a little unnerving. But his bow still has not wavered. Understanding is one thing; trust quite another."

And the end is just perfect, Coulson is quite the sly spy ;)
