As Sideshowme says in one of his early posts, RS&SP are the masters of misdirection and last night they did it again. The whole episode had me waiting for some horrific end game or tragic and shocking finale... but not to be. This particular episode had a nice feelgood ending where the decent people had happy endings and the nasty shits got their comeuppance.
The characters perceived as losers... won!
Also a rare episode where nobody died (or pretended to die)
I think the writers went for a different ending this time around although the ending had a similar feel to the episode 'last gasp' from the first Series.
So on refection, fair play to them for mixing it up a bit.
