Owen could see that he wasn't going to get the chance to explain why he didn't have to right now, so instead, Owen returned the kiss, aiming to keep Ianto from thinking that he'd done anything wrong again. Raising a hand slowly to rest on Ianto's cheek, Owen pulled back from the kiss slowly, smiling a bit at him as he did.
"I'm not going anywhere, Ianto," Owen said softly. "I'm right here. You don't have to do anything to keep me here. I'm not the Master, and I'm not Jack. I don't want anything like that from you. Just your presence is enough."
