Too wiped to go listen again but you could be right. I thought I caught someone asking at the end if they had BB's number (like for future contact?) and her mom saying she had her phone (which I took to mean then/that day).
I now just finished watching the QX and BB video, it was worth it to go watch it again but that was two of them and it took me some time to find both
Watching the QX one in hindsight I found worthwhile. There is much that was not said. And much that was said. It was the day after the car was located which I also could not have remembered if I had not looked back, or believe it was, May 9th (car), May 10th (QX).
