The speech aspect of this is really interesting.
My first instinct would be “don’t make this about me.” Think about what you would say about him, how you met, adventures and escapades you’ve gotten into and out of, and how you’ve grown from who you were when you met into the unique and interesting people you are now.
I think that’s a sly way to talk about it without making the whole speech about it.
This is an interview with another reporter from ProPublica who also reported on this, not an interview with the people themselves.
