There's a cool bit of imagery from Small Favor that I don't see get brought up enough, from Marcone and Ivy's rescue.
Sanya has given his Knight's cloak to Marcone. Understandable, since it's cold. Harry takes a moment to mention how Sanya's large cloak doesn't fit Marcone's smaller frame. Then later we get to the moment Marcone and Ivy are winched up to the helicopter:
The line came down with a lift harness attached to it. “Marcone,” I shouted over the sound of the rotors and the minigun—which is to say, I was more or less mouthing it exaggeratedly. “You first. That was the deal.”
He shook his head and pointed his finger at Ivy.
I snarled and pushed the girl into his arms, then started slapping the harness over him. He got it after a second, and in a couple more we had him secured in the harness and holding the semiconscious Ivy tight against him. I gave Luccio the thumbs-up, and Marcone and Ivy went zipping gracefully up the line to the chopper, wrapped in the white cloak, the scarlet crosses on it standing out sharply in the winter light.
If such striking imagery--shown during a moment where Marcone is acting on his better morals--isn't some kind of foreshadowing, I don't know what it is.
... Nothing, is the answer. It could be absolutely nothing.
