The Jack and Ianto love story which has been forever blossoming since day one plays a huge part in the upcoming series, according to Euros Lyn.
"I think that the Ianto and Jack love story is really integral to season three," the director said. "It 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."
He added: "It's definitely worth tuning in for season three to find out what happens to them!"
Torchwood - Children of Earth will air over 5 consecutive nights on BBC One later this year.
