Thanks for clearing that up, Clay.
MrFluffy, I don't think it was his accent that muddied it for me, more the fact that aspirates ("H"s) are unclear in real life let alone recorded. Interestingly I might have found it clearer if we hadn't been shown the name on the "licence plate". As I say, it wasn't a biggie, I just missed it the first time.
As for the surprise, I see what you mean, but to me the fact that the Welshman was a messenger from God or even God himself - certainly "other worldly" was clear from the time he produced the "Matt" licence plate - and it seemd (to me) totally appropriate that he disappeared as he did. A nice touch, but no surprise here.
Back to the name - he clearly say's "Anna" rather than "Hannah" at the end. Whilst the names may mean the same it does matter. It should be clear it's the same name. Unless you're aiming for ambiguity.
OK I'm quite happy with the closing line being deliberately open ended (thanks for explaining that - I was obviously looking too deep) but I don't really understand why he should want to tell her anything.
In fact one interpretation might be that if he's just had a revelation that he's responsible for his own life, his own personality and he's not the product of what others tell him he is, then the
first thing he might question is why on earth he should do what this stranger has told him.
Still, it's provoked discussion, so to that end it's been a success
