We've had such a close relationship with the fans. Through social networking and the internet, we have much more contact, and we did go to things like Comic-Con. So, I think people know most of our secrets.

We didn't know until really quite late in the piece how Joel [Wyman] would finish it off.

I loved playing Walternate because he was completely the same character, version 1985, and then it developed in such a different way, physically and mentally. So, to be able to play that, in the same television series, as playing the other ones was a fantastic gift for me.

I'm truly grateful to the writers of Fringe for giving me that because, over the years, when I've spoken about the character with them, I've always felt that this would be the perfect way to end and complete his journey, and to complete the journey of this series, and they gave it to me.

You're always working with the relationships. It's pretty demanding, but then again I love that.

'Fringe' is essentially a love story, so the scenes where Walter had close connection with Peter, but also with Anna's character or Jasika's character, were very special to me.

A lot of the times, roles are chosen for us.
