I'm back! (with a broken heart, maybe, and it might be because of Broken, but who knows? Beh, not me! (Listen to it. Or read a transcript (I actually did one. Yeah I was bored)))
Posting after That's A Promise is easier for a sequel. Anyway here's the summary:

"Two years have passed since Ianto joined the team. They moved to a new city, they learnt how to work together, they became friends (well, mostly), but don't they all have secrets? Some are just more dangerous than others, like Owen's. Some are just painful, like Ianto's."

I still haven't finished it and I'm not sure where this is going but I wanted to post it! Anyway, thank you for your support, I hope you'll like it!
As I didn't want it to be something right after That's A Promise and had initially planned it to be all about Owen, I actually haven't put a lot about the two years, (and not everything right away) but it's not needed for the fic. If you have questions though, I'd be glad to answer. And, last thing, the chapters would be shorter than before.

Warnings : references to child abduction, past suicidal thoughts, graphic depictions of violence and torture, aftermath of torture, minor character death... It trully is way darker than the first part.

Part. 2: ... And Lies.

Owen looked at the view his new flat offered and had a small smile. Okay, nice. He didn't regret buying it.

He had a huge window, allowing him a direct view of the bay and beyond. Cardiff wasn't as awful as before, with this new acquisition.

Though, he still missed London. They had moved in Cardiff two years before, and it was what it had taken for Owen to be able to buy a proper flat. He had first been in a collocation with Gwen, which was the worst idea ever – no, moving to Cardiff was way worse – because each time they would argue (which meant, a lot, considering both their behaviour), Gwen would use her power to cut the power off when Owen was taking a shower. And Owen would freak her out or play pranks with his ability to change his face.

It had been fun, but not for long, and he had quickly abandoned the idea to take a flat on his own, but a small one. Now he had a huge one and even if he was living alone, it felt good to have that much space.

But still, he hated Jack for making them officially settle in Cardiff. And the Doctor had been happy about his initiative...

Owen grumbled to himself, remembering Jack from two years ago. Being captured had changed him, especially because of Ianto's presence. Owen didn't like him. Well it was not that he hated the young man or anything, more like he didn't really mind his presence but felt as good when he wasn't around. Truth be told, he was pretty scared of his power. It was dangerous for all of them to have someone who could suppress their powers, or who was pretty vulnerable, and Ianto was both.
He sighed, disappointed in himself for thinking about this rather than anything happier, such as the view, his job mostly satisfying, his new flat, his quite good one night stand the day before... No, really, his life was quite good if he were to be honest. Nothing was ever perfect.
But again, why was he even thinking about this? He usually didn't care much, he was efficient in his job though complaining a lot, he did it and that was it. Lately, he seemed to like his routine, and seeing the team every time, and working for Jack... it made him feel at home, finally. With people he sometimes hated as much as he loved, but that was the cons of spending the entire day together (and it was essential in a good friendship for him), a flat he was now quite happy about...

Really, Owen had nothing to truly complain about - though he still complained a lot but he was just being himself. He was fine, everything was fine, he thought when he opened his mailbox. Well, not quite right away because some paper couldn't do any wrong, but the content of one could.
When he read it, he decided to ignore it. Everything was fine, right? Nothing to worry about.

He ran back to his flat, threw the one paper on some table, and left in a breath. He managed to forget about it while at work, enjoying a new fight between Jack and Gwen that always ended the same way since Ianto was in the team. Gwen yelling, Jack shouting back, Gwen wanting to cut the power off of his computer and Ianto throwing a warning look at her. She would usually stop there and storm out the office. Except that Ianto had said or done nothing to defend Jack and Gwen was even more pissed off than usual, so was Jack (Owen's bet was that he and Ianto had had some sort of a fight though he had never seen them fighting) and it had ended up with Gwen throwing a mug across the room. She obviously had tried to electrocute Jack, but this time Ianto had reacted and shouted. For the first time in his time here, he had yelled in front of the whole team. And it was efficient, as everyone had stopped dead in what they were doing, Tosh and Owen as well, to look at Ianto as if he were some kind of an alien. It had been fun to see Gwen and Jack apologize with great shame to a 21-year-old when they both were older. Ianto had prevented Gwen from using her power again the whole day, saying that even if Jack could heal, he could still feel the pain and there were no reason to hurt him more. Gwen being powerless and speechless because of Ianto was the main (if not the only?) reason Owen really liked the young man.

When Owen got home, he forgot about all the fun when he saw the letter. He read it again, a lot, just to be sure that he hadn't dreamed. He clenched his fist on the paper, not caring about tearing the letter, and took his time to weigh the pros and the cons. He owed them his life, after all. It would erase his debt, definitely. Maybe he could do it one more time.
