A few years ago, in MarinaNova, he did have other people he could have talked to about this, people he'd built real, deep relationships with through being forced to stay still in one place for a decent length of time. Through being forced to actually engage with people properly because he wasn't able to distract himself by flitting about through the universe. Even Saavi and Taiana hadn't known him as well as some of those people back in Marina (Chuck, for instance, and Kitty) simply because of all those distractions - though that didn't mean his relationship with them hadn't run deep too, just in a different way that was less about deep, personal revelations and insights and more about sharing physical intimacy and wild adventures.

More like what his relationship with Ianto had been pre-MarinaNova.

He shakes his head. "I examined all the wreckage I could find, and I'm pretty sure it was an accident. There was a fault in the engine - Taiana had been warning us for months that the regulator needed replacing but we'd kept putting it off for one reason or another. I'm pretty sure it was that."

And of course he's blaming himself for not taking the time to get it fixed.
