(I'm stil listening to Cariad...)

The first part was so wonderful because Ianto is that perfect and it would not surprise me that he does know how to speak all those languages.
You know, I do wonder what does Ianto (canon Ianto) feels about the Doctor due the whole Canary Wharf issue.

And then I was so emotional with Ianto thanking the Tardis and Jack playing with his necklace, but what did the Tardis did?!!!
