The time span (SPOILERS)
So the final episode jumps six months, then one year, then six years... does this mean the rest of the series takes place around seven and a half years earlier, i.e. 2007. I was never aware of this as I was watching it... and at one point (the v-log episode) they spoke about v-logs being "way back in 2006". Surely they would say 'last year'...
OR do we simply jump into the future from the present day?
I have to say they aged Henry perfectly across the six-year time-leap.
And I assume there will be no second series of this, partly from the time-leap in that final episode and partly because RTD mentioned his next project is about HIV.
