A close call does not always go unpunished.
As per the day before, it was already well into the evening by the time David awoke from his uneasy sleep. Almost as soon as he did, he heard signs of life upstairs. Unlike the previous day, Twilight seemed to spend much more time in the library. Spike, as well, was much more active. The man hoped to, at some point, figure out the unicorn's routine. A creature of habit and organization, a consistent schedule was not out of the question.
Because of the proximity to the true denizens of the library, David's day was much more inactive, fearing discovery if he made too much noise. He spent most of the day trying to determine what language one of the books was written in (because it surely wasn't English), until he grew bored. In his boredom, small, inconsequential things he wouldn't have noticed with everything else going on came to light.
Smell. Despite not bathing for two days now, he did not seem to have an odor. Surely if he did and merely did not smell it himself, it would have revealed him to those who dwelt upstairs. As well, despite eating and drinking since he arrived, he had yet to have the need to...relieve himself. That part he did not put much thought into: living in a basement without a bathroom, not having such needs was more than just convenient. He'd rather not look a gift horse in the mouth, so to speak.
Sleep had become different to him as well. Instead of spending potentially hours wrestling with his own thoughts before falling asleep, he had managed to fall asleep faster than he had ever done before, numerous times now. Even the night before, being rattled by his close encounter in Sugarcube Corner, he was able to sleep in only a few minutes of resting. Interesting.
Eventually, those strange thoughts grew boring as well, and the man resorted to eavesdropping on his unknowing housemates for entertainment. A part of him felt both concerned and ashamed for this act, risking discovery by getting closer to the door, and listening in on potentially private matters. But another part of him was bored to tears, and that part seemed to be winning.
Twilight seemed to be organizing the library through most of the day. This was interrupted occasionally by a few small magical experiments. Spike was present as well, helping the unicorn with her activities. Their conversations were not particularly interesting. That is, until they got a visitor.
The pink one had returned.
As soon as Twilight opened the door, he knew who had come to visit. The sound of her voice carried through to all areas of the library, and probably beyond. Twilight and Spike did not seem affected by it, however, and greeted the earth pony happily. The three began to chat idly, resuming the conversation David had very little interest in. That did not last very long.
"Oh, Twilight, did you hear? Cheerilee said she saw a big spooky monster tiptoeing around Ponyville last night!"
Oh shit.
"Really? I wouldn't think 'big spooky monsters' would be ones to tiptoe at night, Pinkie."
"Maybe it didn't want to be rude and wake up all of Ponyville! A considerate monster, I like that!"
The unicorn let out an amused sigh and the conversation seemed to stop. He could hear movement around on the first floor, and assumed it was Pinkie trying to find something to amuse herself with. Suddenly, a loud noise emanated from where he guessed the earth pony had been standing, prompting a response from both Twilight and Spike.
"What does that one mean? I've never seen it before," the unicorn asked.
"I'm not sure. It must be the new one! It woke me up last night. I thought it was telling me to get a midnight snack!"
The pink pony hesitated.
"That's funny. Its not midnight, and I'm not hungry. I guess I was wrong about what it means."
After Pinkie finished speaking, Spike let out a loud sneeze.
"Oooh, a sneezing Pinkie sense! That sounds like a fun one!"
Twilight sounded as if she was going to respond, but the words died in her throat and she remained silent.
David let out a quiet sigh of relief, having retreated down the stairs as soon as he realized what they were talking about. That Pinkie sense was going to be the end of him. And not only that, but now he had almost been discovered without him even knowing. It didn't seem like they believed the story, but it could mean more dangers at night. Things were not getting any easier.
Thankfully, his supply of cupcakes and his incredibly rationed soda bottle were enough to get him through the night. No leaving the library tonight. It was best to lay low, throw off any ponies who might be on the look out for a 'big spooky monster'.
Thus, David spent his night in the library, attempting to read more books. Before he was about to sleep, he made a quick entry in the journal:
"The pink one is out to get me. Avoid at all costs."
