Achingly beautiful! Ianto is so caring and considerate, and as always highly observant - he notices the tiniest things, anything that isn't normal for Jack, and acts to comfort and reassure. And he won't push Jack for details. If Jack wants to tell him later, Ianto will listen, but he won't demand answers. Gwen seems to think she has some kind of god given right to demand answers to questions she really has no right to even ask. She also seems to be the most heartless and inconsiderate member of the team, imho, not least for the way she treats Rhys and her team mates. No one deserves the title of 'The Heart of Torchwood' less than Gwen.
