His boots crunched loudly as he walked into the main area of the entire room despite not stepping on much of anything, and his deeply interested gaze swept the hundreds of bookshelves before falling on the giant mountain of books just sitting there in the middle of the floor. He could clearly see that it surpassed the height of his head and was way wider than he was thick. A very confused Alicorn and a disgruntled dragon followed him from behind.

"Hmmm...That is one big pile a' sh!t. " Negan stated the obvious as he tapped his baseball bat on the floor in consideration. "...It is informational though. There's always that."

Spike scowled at the crimson liquid dripping from the bat. "You're getting blood on the floor."

"Eh, that'll come up with some lemon juice and baking soda. Believe me, I would know."

"I...uh...this...this doesn't make sense." As usual, Twilight's brain didn't seem to be comprehending what was going on here. She trotted to a stop in front of the man, her height settling just at his waist and near enough to the bat to sicken her. "How did you even get here?! Why aren't you a pony?!"

"I dunno." Negan shrugged halfheartedly and picked up a book titled "The Hatchet." "Why is he a dragon?"

"Because dragons are just natural born here! There are no humans in Equestria! Even if there were, they'd be ponies!" Twilight frowned deeper when he realized that the man was ignoring her, skimming over pages of the book he'd found. "...Do you at least know how you got here?!"

Negan tossed the lame book over his shoulder nonchalantly and reached into his jacket pulled a rather thick book with no title on he front of it. He handed it to Twilight, who levitated the book to her eyes. "By way of that bucket a' fun! I've been reading the things it records about you lovely folks and at the same time, I just so happen to find a little mirror on the last page."

Twilight grimaced with horror as she discovered that the book had detailed events in her life, almost as if the pony who did this were standing next to her the whole time. the Alicorn reached the end of the book and saw a a mirror the size of the page, but with no reflection...just an infinite swirl of color. It didn't take a genius like her to recognize it as a portal very similar to that of the one she used in the past.

"I don't know who's in charge a' books like that, but they do a baaad job of keepin' track of 'em." The human used his bat to sift around a couple of other books, and look at more pun-filled titles. "Can you believe my luck in finding it and discovering that it can take me all the way out here?! That's the coolest thing ever!"

Spike didn't wish to study the book as intently as Twilight was, so he scrutinized Negan again. "So you came straight to this castle because...?"

"Aside from me bein' so plum bored? The book mentioned you being in charge of this here library and running short on the staff to help ya run it. Well today's your lucky day!" Negan announced, his voice imitating that of a auctioneer on some serious drugs. " 'cuz fer the low, low price of whatever currency you got in this place...I will be willing to put forth my effort in organizing this heap of mess behind me."

Twilight completely dropped the book and stared at the impossibly grinning face of Negan, who added in a wag of his eyebrows for effect. She opened her mouth to start talking trailed off into silence and then opened her mouth again. "You want to work here?"

Negan huffed out a laugh and tilted his head."That's what I said, Darlin'...I mean, Boss!"

"Twilight?" Spike coughed suspiciously into his fist and gestured to the fresh, recently shipped library tables nearby. "Can we,uh...talk for a sec?" After casting her guest a reluctant grin, Twilight followed through with her assistant's request. "So, we're obviously not letting him work here, right?"

"...He did come all the way out here to get a job." Twilight pointed out against her feelings. "It doesn't seem so nice to send him back empty hoov...handed like that."

Spike glowered more.  "But he's got a bloody baseball bat! Clearly that's not a good employee to have around! He could be a bad guy, wherever he comes from."

"But we always reform villains when we can! Discord was a bad guy, and look how he...Look how Starlight turned out! She's one of your best friends!"

"I don't think we're gonna be friends."

"You never know what can happen at a job! We'll give him a chance." She lowered her voice a bit more. " If he turns out to be as bad as you think, I'll send him back where he came from and seal the portal. Otherwise, be on your best behavior."

Spike gave a childish grumble and crossed his arms, which Twilight took as acknowledgement. Negan, who had obviously been trying to eavesdrop on their conversation, stood up straight and offered one of his signature grins to her. The alicorn reconsidered what she was going to agree to, and spoke: "Mr...Negan. Would you mind taking a seat until I come back with the application? You may set your weapon in that corner over there."

"Well, Sh!t! Looks like you get to sit pretty somewhere, Lucille!" Negan told his bat with a skip in his step, letting it lean against the corner of the room as specified. Twilight exchanged a glance with Spike before trotting off in search of the application papers. Spike didn't make any eye contact with the 'guest', but that didn't mean that he couldn't hear anything from him. After all, it was only four seconds before he heard:

"Hey kid...Y' got anything t' eat? I'm hungrier than a lotta folks back home are nowadays..."
