Okay for clarity ....
1.52 seen in Pedi - photos above - police confirm it is him (and is 20 mins after left beach, so timings right for a 15 min walk), so Yes made it to Pedi.... unknown what happened after that (and could have fallen into sea as one of the routes to Symi Town where his friend's villa is, is coastal)
4.30 photos in Pedi - these haven't been circulated, I think? These are ones his wife Clare says aren't him...
Have I missed anything?
