I just need to get something that's been bugging me for ages off my chest - I can't match up the assumptions which I'd made about Leo and Hal based on Hal's prequel and what Leo tells us in Hal's dream at the end of S5.....

I'd always imagined that Leo had been living in this country for a while when he was imprisoned by Hal.  This was as assumption based on the fact that his dream was to open a barber's shop in Southend and live a quiet life - not what I would expect to hear from somebody who had newly emigrated to this country.  Would anyone really emigrate to this country with plans to move to Southend?  Not that I've got anything against Southend....but I'm sure it's not an internationally famous destination!  I'd assumed that this was a dream born out of disillusionment with life in London, prompted, perhaps, by his newly aquired werewolf curse.

I find it hard to imagine that Leo would've emigrated to London if he had already been a werewolf.....I'd assumed that he'd been turned whilst living here - in fact, I'd imagined the possibility that he'd been caught by Hal as a human and had been turned during one of Hal's dogfights (like McNair).

But according to Hal's encounter with Leo at the end of S5, these assumptions are contradicted.  Leo apparently arrived in London with the promise of a job on the Underground, straight off the boat and already carrying his curse, when he was met by Hal at the station. 

Of do I just spend waaaay too much time thinking about this stuff.....??
