Season 2 starts in the states 30th October. Which is the same time of year that season 1 started so I would assume that it will start over here the same time that it did for season 1 too.
Funny enough I switched on the TV the other day and it was mentioning Season 2 but I literally caught it for a second or two so didn't see/hear any more than a few scenes from Season 1.. I think it might have just said coming soon on 5. That's not too helpful though is it?!
