Yes am hoping that one of the posters comes back on to re-explain, I don't have the energy.
( Like you, I also thought JT's comments might be very significant, at the time he made them, because I'd spent a lot of time trying to establish how little time the couple might have spent in the same house as Chris & Roberta)
Ditto her comment to LE about her drivers licence wtte ' it's from out of Florida right now'
( may be reading too much into these things ofc, but the latter cld be signif)
A couple of other posters - Lee? - thought Fl was also poor for work options for young people & it looks like they're going to need* jobs soon
* How many followers did they have on their platforms, prior to the disappearance? Insufficient?
