Sirius pulled James close when he finally did join him in bed, returning the kiss before he shrugged. "I got a few," He drew the word out for a moment, "minutes - I'll live though. It's not the first time I've gone without sleep and I'm sure it won't be the last."
And he didn't have any plans that day so he wasn't too worried about how he would function during the day, and with James there now he might even get a few hours of sleep now. "How did things go last night?" He asked. He could tell James was tired, and the admission that it had been a long night was more telling than many other things would have been.
