"Yeah," John allows, because he knows how that feels. He didn't exactly get much in the way of days off either. He pulls the gently glowing alien tablet from one of his pockets, checks it again to make sure no shamans are sneaking up on them. It resolutely shows him two dots, surrounded by darkness.

There aren't going to be any days off here, either. No holidays to see your family. Is Dave in the pods? John realises with a jolt he never asked for him to be saved, so he doesn't know if he is. Or how he feels about that. Did Ianto ask for Rhiannon and her children to be saved?

"I can take the first watch," he says finally, "if you want to get some sleep."
