JMO
On last Dateline episode (at 25:30) DW said "When I went to say goodbye only Lori was there..." etc
IMO they (MG and DW) stayed overnight not at LV's place, but somewhere else
ETA: Ok, I checked the CD's Affidavit, it says that they were recording the podcast that night (would that be in LV's townhouse or somewhere else?)
It also states: "26. 'DW' further informed us that when he woke up the morning of September 23, 2019, he asked Lori where JJ was."
So I wonder if it's probable they were not in LV's townhouse during that night?
Or they were staying at LVD's, but no breakfast, just "going to say goodbye" and leave
