>>975 I think the only flaw in this argument is the idea of Tom having large luggage and small luggage!!. I think the small wheeled bag we saw was the totality of Tom's luggage for the entire trip to the US. He may well have gone to San Diego with only the backpack for a single night - he then returns to the Four Seasons to collect the small bag.
Did I see something about TS's plane having gone to Nashville?
If so anonsy' theory seem sensible. They arrive in LA. He checks into the 4S becaus of reasons (allergic to cat hairs, wants to pretend to her parents they aren't sleeping together, still keeping up some bizarre facade for the press, whatever). They spend the night of 21.7 together, probably at her place, and are driven to the gym separately the next day because she is going home and he is going to the 4S then to his agent. He goes to agent then to SD. She stays home night of 22.7 then flies to Nashville the next day. Or flies to Nashville that day. Hence no stop off to see her before checking out of the 4S. She's already left LA.
