Do we have accurate timings? It was the 8am bus he missed and then spoke to the neighbour who then left shortly after and drove past him heading up the road? Sky says the Lucy call was at 8.15, some say 8.30, BBC 8.30-9? That's not a long period of time to get lost, we know he was on the road so even if he turned off and then the call happened he could have returned to the road if he was thinking clearly
- 'Needing a drink' shortly after leaving the airbnb (where he could have got water)
- Suggesting he was walking 10 hours home
- Heading the wrong way
- Cut himself
JMO but i don't think he was in a coherent frame of mind (beyond just dehydration/tiredness). Would be really interesting to get the neighbours assessment of how he seemed and if anything was taken back at the airbnb with the two guys
