It was the act of imagining herself as she had once been that enriched her syntax and extended not only her images but the coherent flow of association that led directly into the task at hand.

The better the speaker imagined herself, the more vividly she brought the dead doctor to life. It was, after all, a baptism by fire that was being described. To see her ambitious young self burning to know what her mentor knew, we had to see the mentor as well: an agent of threat and promise: a figure of equal complexity.
