For ages, Jack associates Ianto with coffee. It can’t be helped really. Every time he turns around, there’s Ianto with his pleasant smile and a tray of blissful caffiene balancing on his palm.

But eventually, Jack begins to belief that Ianto was not so much born as sprouted from a coffee bean.

He's rich and dark despite those same pleasant smiles. There's a depth to him so easily masked by everyone's lighter assumptions. It can be covered and it can be flavored differently, but it doesn't change the truth of the original thing. Coffee and Ianto are so much more than what they appear.

So Ianto doesn't just bring the coffee. He smells like coffee. And in truth, he might actually be coffee walking around on two legs and a finely tailored suit.

It doesn't take very long at all for Jack to wonder if he tastes like coffee too.
