Good old DM. Shouts about the "last man to see her alive" then goes on to say the last man to see her alive was someone completely different.
Interesting that her conversation with this Spanish man, from which a couple of hinky questions arose, was conducted in French while wearing a face mask. Hardly the most reliable information exchange.
She said she was going to French town of Bagneres de Luchon and mentioned the city of Toulouse.
This story of hiking to Luchon and the on to Toulouse does not hold water IMO if you compare it with her actual situation.
She had left the campervan in Benasque, presumably at a parking lot for motorhomes. That is a
paid area. You pay for the van, even if you are not there.
So what was the plan, going home to her partner and then
oops... I think I forgot something ?? (and how will we get back to the camper given the curfew?)
What I think
may have happened is that ED, masked, English, French not her first language, said something like
on this route I can go on to Luchon and Toulouse!
And Mr Ballarin, masked, Spanish, French not his first language but in certain respects very similar to Spanish, understood that that was what she was planning to do, because in French, one would have said 'vers Luchon' meaning
in the direction of. Also, in French, the conditional tense would have been used, indicating that this was not cast in concrete.
Two Brits speaking French understand each other perfectly.
I have my doubts about any other combination, masked or unmasked. Masks not helpful anyway.
This conversation happened on the 21 of November. Esther walked a trail that did
not lead her to the Refuge Venasque. The next day IMO she returned from wherever she was instead of going on in the direction of Luchon. She arrived near the Salvaguardia around 3 o'clock in the afternoon, so she probably came from quite a distance. My guess is this would have been somewhere further north east from Benasque and the Salvaguardia.
This would explain why she was there so late. She might have continued to the Refuge Venasque, as planned, or she might have been on her way through the woods to the town of Benasque. Going to Benasque she would have been too late to make it that day, and she'd have needed a place for the night.
I still think, the Refuge Venasque would have been the most logical place for her to go to. I don't know what her logic was of course.
