Haven't received a reply. I was just hoping someone who is familiar with how things worked, could explain if a couple was in line to board but changed their minds and exited the line, that it's not unusual that there would be no record of them anywhere. Having read other stories here, this doesn't seem unusual. And like one commenter said, if someone never became passengers, they would not be on a passenger list. Not looking for proof of their story recited to me, I already know they told me the truth, but just would nice to have a possible explanation for anyone who may say that story can't be true if they aren't on any list.
