A character from the Doctor Who spin-off Torchwood. He's the "tea boy" of the Torchwood hub. He cleans up after them, gets them everywhere on time, and looks good in a suit, to quote Captain Jack Harkness.
They meant to kill him off during season one, but the audience liked him so much, they decided too keep him.
He is also head the the cult King Ianto's Coffee Club, which is trying to replace tea with coffee as the official drink of the UK. Once he comes to power he plans to off Owen, yay.
Ianto? I need to hear those beautiful Welsh vowels!
Someone: Look isn't that the guy who plays Ianto Jones!
Fangirls: *melt in a Janto puddle*
