Just wondering! Are they still filming?

lolno. The series was filmed last Autumn.

It usually starts in late-September, goes on through all of October and filming finishes around early-November.
The final may be filmed later, but I don't think that's true any more.

Looking forward to seeing how they got on in Edinburgh, tonight! I wonder if Haggis was on their menu!!

Are the ages of the candidates what they are now, or what they were then?

I.e. Gabrielle is supposed to be 29, but is actually now 30?
