What she says: I’m fine.
What she means: Can we just take a moment to think about Ianto Jones lying awake at night watching Jack sleeping. Probably thinking about how he managed to get to this point with this man. Watching Jack sleep and dream, convincing himself that Jack is dreaming about leaving Earth and getting to travel the universe again. Thinking to himself that’s what is making Jack smile while he sleeps. He thinks that even if he survives Torchwood to grow old, Jack won’t be there for it. He’ll have moved on, whether its with the Doctor or someone else. He doesn’t know how he can be enough for this wonderful man who has seen so many things and loved so many people. How can a man like that be happy with an office boy from Wales? So he resigns himself to thinking he’s just something to keep Jack occupied while he’s here. Just a blip in time.
