"Only when the days are eventful," Nathan said carefully. It wasn't quite the truth, there were nights he didn't sleep as much even when the eventful things were somewhat in the past, but he wasn't going to be announcing that. Keeping his hands busy, he stacked stray papers into a neat pile, which joined the notepad and then finally the stack of books. If it had the appearance of someone about to make a getaway, that was likely because it was the case.
"But it looks like I've been up long enough," he said, taking his bowl to the sink and then returning for the stack. Once gathered, he leaned in and kissed her cheek. "'Night, Ma." The gesture might have been surprising when one considered the level of anger Nathan had, but ultimately he loved his mother. He might not like her very much right now, might not believe in her, but he still loved her, no matter how weak that might seem. She was still his mother.
When he got to the door and the handle wouldn't open, his first reaction was confusion, then annoyance – but surprisingly not yet at her. "Damn, the door is jammed," he said, pushing the stack onto the counter and bending to look at the lock. "Gimme a minute, I'll just..."
The locking mechanism wasn't on the inside. It was on the outside. He shook the door handle again, harder this time, and understanding dawned. They'd been locked in. Or, perhaps more accurately, he'd been locked in. The plan had 'Devised and Executed by Angela Petrelli' stamped all over it.
