Also, after playing through a mission where he basically double-crossed everyone (partly unintentionally, I think) and was awarded with many Renegade points, he looked thoughtful and said, "I think maybe I want to be nice to *some* people."
Certain types of foreshadowing, however, are lost on him. He cleared out a room, and got to an elevator at the far end. Garrus said something like, "Wow, we're really out in the open here, especially if there's somebody in the elevator." And Shepherd responded with, "Good thing there's plenty of cover around." Younger Nephew had Shepherd stand directly in front of the elevator waiting for it to open, and was astonished when a bunch of krogan poured out and killed him off. "They just came out of nowhere!" he exclaimed. (After a reload, he pushed the elevator button, got into cover, and handily dealt with the hostile forces.)
I still do the code-matching puzzles for him, but he understands how they work well enough that he sometimes tries to help.
