Hello everyone,

From the book Choose Your Story, Change Your Life by Kindra Hall.
Jonathan and Zara are husband and wife. Some time ago Jonathan had cancer.

The doctor warned Zara it was going to be aggressive. Essentially, they were going to take everything out of Jonathan—all the cells, the bad and the good. He would be admitted into the hospital and not be allowed out for a month.

“She told me to see it as a rebirth. And I liked that story. I decided to fully embrace that story. To celebrate it, even. What a beautiful thing to be completely new in your forties. Few people get that chance.” Zara told Jonathan the rebirth story and shared the doctor’s recommendation to lean into the idea. “Those who resist that story,” Zara said, “have a harder time and less desirable results.” If Jonathan could surrender and embrace that story, too, the mind could help lead the body down the path of healing.

To be clear, Zara ***reiterated the seriousness***: “Make no mistake. This was not a woo-woo approach.” One of the most technical hospitals in the country was pumping her husband full of the most highly advanced medicine that science could create.

1. to say or do again or repeatedly; repeat, often excessively.

Does "reiterated the seriousness" mean that Zara realized the seriousness and repeated to herself "Make no mistake. This was not a woo-woo approach"?

I must admit I doubt my own interpretation because if it is what Zara repeated to herself, why is it "This was not a...", not "This is not..."?

Thank you.
