[RGPargy]

I thought there were 22 or 23 or something but i can only see 17 plus a 2 hour recap special??

18 I think

Oh PS - I am only on episode 15 or something so no spoilers please! Thank you !

offically 18, but 17 & 18 (the final) were bundled together into a 2 1/2hr episode

Ah right, thanx Romilly!
