Nikolai might have a lot of energy for his age. He might be a brainiac and a really smart person outside education, but Nikolai wasn't a restless child. It was easy for him to fall asleep, which was why he had no trouble falling asleep with the lights off. infact, it was what he preferred. He didn't even need to be read to in order to fall asleep, he only loved listening to me read to him just because he considered it a bonding moment.
However, after that episode which I knew left him with a little trauma, he had become restless. It was harder for him to fall asleep, and of course I didn't let Rory know about this because he was only gonna worry his head off.
