[She did almost wonder if they were going to end up talking again. She didn't mind. Lots can happen in just the time it takes to make a decision and then walk to the place to follow it through. But she's kissing him back so readily when he pulls her close. When she's with Chekov everything is tender and intimate and loving. It's wonderful and perfect. She needs that depth of connection. It's a very deeply satisfying experience. With Jack even after being with him more over time, she gets the thrill. The unexpected. It's not routine with anyone, and it's not like she couldn't live without the variety, but there are no enemies to slay here. No missions. No life or death conflicts and she doesn't miss any of that intellectually. But from a young age her body was trained and honed for it. There are settings in her brain built around it. Maybe if they'd been stuck in here with a therapist she could have worked out other ways around this, but as it is her open relationship fills in the gaps.
Of course, in this moment it's not just about her. Well, it's never just about her when she's with someone else. But Jack is obviously hurting and while comforting her friend with sex when the biggest problem in his life is losing the man he loves because he had sex with other people makes no real logical sense it still feels strangely right because it's him. Because this is a language he expresses himself in and she has always been one to comfort physically. Granted, it's usually with hugs and holding, but she's gotten to know Jack pretty well and she has some idea of how to make this better at least for a little while. Nothing can distract you from a broken heart for long. It just hurts and hurts until it finally hurts less. It might help to stop picking at it and she suggested as much when she encouraged Ianto to consider moving at least. But she knows how strongly you can want to hold on in these situations. It's been reminding her so much of her and Reid even though that was decades ago now.
But there are really only so many thoughts that can spin through her mind when Jack is kissing her and as she presses closer and deepens the kiss the rest tends to slide away into the hum of the background.]
