MrsKo - see if you can YouTube some of the previous episodes???
I don't think they have released a DVD of the first series yet but if you know someone who is a tad tech savvy there is other ways of getting your hands on the first season, iykwim??
Watching the first series would certainly help to make more sense of the show but if you can't get a copy, sing out and we can fill you in on what's happened so your up to speed
I just love it. Having worked in Mental health for a number of years before having my kiddli-winks, I relate back to some of our clients. Toni Collette truly plays the part phenomenally and depicts Tara's character so well especially when she takes on the alter roles.
