How do you know for a fact that Gillian spent a week in L.A. before the GG? IIRC she was spotted in Cancun few days before and then in L.A. the day of the awards. Are there any other sightings I don’t know off? Can you link me?

I don’t know for a fact she spent a week in LA before the Globes, but I assume she spent a week there after the Globes.
She was only spotted in LA a few days before the Globes, if I remember correctly, and then nothing for a week before she reappeared in Davos and David reappeared in NY the same day. I just find every disappearing and reappearing of them at the same time very suspicious. But I don’t know for fact.
