Dan carefully put his arm round his dad's shoulders as Shep offered to get him a drink, although he wasn't really up to holding on or anything like that. He leaned into Jack as they stood there, and then his brain fired off a thought that made him try and stand up straight on his own again. "Both of you. You, you can't," he said, not quite able to coordinate himself as he spoke, "your knees and... and it's gonna hurt. No, I can... don't."
He couldn't quite manage standing at that moment in time, though, and if Jack and Shep decided to set him down, there was little he'd be able to do to stop them. Fuck, he couldn't even deal with having a hangover properly. Such a fuck-up.
