Jack and Ianto's love is integral to the plot of Torchwood S3, says Director Euros Lyn

I think that the Ianto and Jack love story is really integral to season three and takes us on a journey and allows us to explore the nature of their relationship in a way that has never happened before on Torchwood. So it's definitely worth tuning in for season three to find out what happens to them.
