The colour drained out of Owen's face as he turned to look at Ianto, a frown creasing his forehead and his mouth pulled into a scowl.
"How the fuck do you know about her?"
"When you were hired, Three was still connected to One. Jack had to inform Yvonne that you had been taken on. He had to let her know why. Officially if she didn't approved, Jack had to get rid of you, but Jack was rogue at this point anyway. She called Three the rescue centre when she found out. Never told us why but she always said that Three was where all the lost and lonely people were saved. We never knew why until the report and your details had been sent through a couple of weeks later. Lisa had to type them into the database and I had to file the originals."
"That thing knew?" Owen spat.
"She wasn't a thing! She was my girlfriend! I tried everything I could to save Lisa, I never gave up on her. Just like you never gave up on Katie, just like you fought for her!"
"Don't you ever say her name. Do you hear me? Don't you ever talk about her again." Owen shot back, striding over to where Ianto was sitting and pushing him back.
"You're not the man you were then, though. Are you? Her death, Jack... they've changed you. God, you've forgotten how in love you were, haven't you? I thought you'd understand, but you're too bitter, too lost. I'm sorry." Ianto stood and turned to walk to the kitchen when Owen pulled him back and punched him.
"You have no idea about the man I was. You have no right to presume anything about me! And no, you twat, I don't understand. I don't understand how you could bring that thing into our base when you saw what they did at One. I don't understand how your small, pea sized brain thought that you were able to save her. And I don't understand why you think you can compare Katie to Lisa. Lisa killed two people in cold blood, she wasn't fucking HUMAN. Katie was -" Owen let out a frustrated growl, kicking at the sofa before turning to his bag. "Katie wasn't like Lisa. She was just a victim."
Ianto watched Owen carefully, cradling his aching jaw. "Can't you see that Lisa was just a victim too, Owen?"
"Maybe at first she was, fine. But you kept her alive in that unit and you fed the cyber technology. You turned her into that machine and you didn't even notice. For fuck's sake, Ianto, the machine turned you into her victim! It played you and made you believe that you could save the woman that it took over. And you're too blind to see that."
"NO! The conversion-" Ianto argued.
"'Wasn't complete', yeah, you've said that."
"I could have saved her." Ianto cried after a tense, silent moment, a tear running from his eye. "I need her. God, Owen, what am I meant to now? She was everything!"
Owen didn't turn to look at Ianto. Instead he stared at his hands as he thought. He was exactly the same after Katie, asking Jack the same questions. He remembered the quick change in moods; depressed on minute, angry the next... He could relate to what Ianto was feeling right now. So why couldn't he say that?
"I don't know. I don't know, Ianto. I can't help you." He whispered loud enough for Ianto to hear.
Ianto nodded and sat back down, closing his eyes to stop the tears.
"I can't help you. Not after -. Things have changed and you have to get used to that now." Owen turned and looked at the man on the sofa; he was so small against the cushions of it, so lost and Owen wished that he could help it.
"I'll be back once a week to check on you. Make sure you're still healthy." He said, waiting for a reply. When he received none he picked up his bag and walked to the door, stopping when he heard Ianto call him.
"I am sorry, Owen. For -" he sighed. "For everything."
Without a second glance or comment back, Owen opened the door carefully and left, wishing that he was more of a man to get over the betrayal and help.
