"Because that's not the only way that people can care, Yan," Owen said softly, hugging Ianto. It was hard to think about how to explain it. It was one of those things that was just understood. But obviously Ianto's natural understanding had been stripped away. "Friends can be close without physical intimacies like that."
Hell, he and Ianto had barely exchanged glances before, and frankly, this was probably the first time there had been less than two feet between them. But that didn't change the fact that Owen had cared about him, thought of him like a little brother.
"You're like family to me, Ianto, like a younger brother. And you don't snog your little brother."
Unless your family was even more messed up than Owen was used to.
