You and Lucifer had ducked into a little book shop. You found that small stores like these often carried informational journals and bestiaries. That's what you told Sam and Dean, Lucifer had guessed on his own the real reason you liked to visit. You loved the smell of the books and the cozy feel of a tucked away nook when you wanted security.

After a while Lucifer began to join you, if anything it only made you feel safer. It did at least.

You walked in with your hand linked behind you, scoping about for a private area for the both of them. Lucifer must have found it first because his arm snaked around your waist, pulling you back into a corner behind a bookshelf. He fell onto the loveseat, the inertia pulled you to sit sideways on his lap.

With a bubbly giggle you hid clutched the collar of his shirt and buried your face in his collarbone. He chuckled lowly, but when you removed your head you could see the restrictive grin spread across his lips. Reaching behind you to the bookshelf, you pulled out a book.

"What are we reading today?" Lucifer murmured into your hair, breath tickling your ear as his arms circled tighter around your waist. You shivered and he smiled a devious little smirk. It was his signature smirk, the one that got under your skin and made you blush with a single glance.

You blushed and pulled it in front of you. Beauty and the Beast. Lucifer scoffed, "How fitting", you could see him roll his eyes in your peripheral vision.

You snorted quietly, and murmured "Luci, you are the farthest thing from a beast in my life." Lucifer glanced at you after you spoke, but your focus was buried in the introduction.

You both read silently from the book for a while before you heard it. The voice shelves away made you tense. Your foot that had been bouncing on the other side of the couch stilled immediately. There was an unsettling chill that gave you a shiver of a different kind.

You did a skilled job of recovering, resuming movement. Though your stillness didn't get past Satan though, he placed a hand over the book to get your attention and curled his arm even farther around your body. Your legs curled into his side and your body turned into his, but wouldn't look at him.

Lucifer was having none of it, he turned your face up to his. His head was less than an inch away with his hard expression and serious eyes. It was obvious his carefree mood had gone out the door with yours, he only thing you couldn't tell was if it was you he was mad at.

"What is the issue now?" He pressed, low and heavy voice clear with concern despite the stoic word usage.

You shook your head, eyebrows furrowing and attention finding the fairy tale novel in my hands interesting again. "There's just someone I used to know here, that's all."

Lucifer leaned his head back, "ooooooohhhhh." Despite the patronizing chord and action you could tell he was still worried. "Old friend you don't want to say hi to?"

You scoffed and turned the page, you weren't even reading anymore you were so jostled. "More like ex, boyfriend that is. My ex boyfriend from before you." His entire demeanor changed when you mentioned ex boyfriend, He seemed ready to get up, assert the dominance and show him whose you were now.

It was when you mentioned that it was the boyfriend before him that his demeanor changed again. His face lost all expression, eyes and skin growing colder. A seething frown settled in place of his former grin. His arms moved around me and he lifted, swinging around and gently setting you to rest on the sofa arm on the other side of the couch.

Your hands shot out and gripped the sides of his over shirt, he pulled off my hands and began to walk away. You shot up and attempted to push him back, whispering to him with urged tones.

"Luci, no, comeback, please. Forget what I said." Your being in front of him meant nothing but your pleads made his eyes shoot to you.

"This man- boy, took a beautiful mind and tore it, crushed it. And then built it back up only to repeat his actions again. He put you in an asylum and on a suicide watch list. I will not let him get away with it. Now excuse me, dear."

The though of what Lucifer would do created a ball of anxiety in your chest. Slowly you followed behind as he strutted forward, easily spotting (E/B/N) from your memories.

Seeing him made you gasp, but you stopped breathing when Lucifer made the first hit. (E/B/N) looked at him incredulously, "Who do you think you are?"

Lucifer smirked chillingly, "Watch your tone, boy. It's Satan your talking to." He threw (E/B/N) to the floor and struck again, and again, and again. He only stopped when the owner ran out and told him to take it outside.

Lucifer stood, grabbing the collar of his shirt and dragging him through the shelves. Bonking his head on corners along the way. You scurried after them, ignoring the looks from other patrons.

It only worsened when the exited the building. Lucifer threw him to the ground again, smashing his face into the ground, blood spattered from the cuts. (E/B/N) was bleeding, bones visibly broken, and awfully confused.

"Lucifer, that's enough, stop", you cried. Your hand reached for your face, upon returning wet, you realized that you were crying. You hadn't even noticed. Lucifer ceased his actions, then hauled (E/B/N) up, shoving him flush to the wall.

Lucifer placed a finger to the others temple, "For (Y/N)." Despite having one eye swollen shut, the other widened like a saucer. He looked over at me, and an expression of fear overtook his face like you'd never seen.

Lucifer never took his eyes off him, "You shall endure the same punishment you inflicted for the rest of your life. And when you think it's over, when your ready to end it, just remember that when you go to hell, I'll be there waiting."

After that, (E/B/N)'s eyes glazed over, a blank expression overcame the fearful one and you gulped. Lucifer let him sink to the ground and turned to you, taking you in his arms. The look of disdain on his face nearly made you sob.

"It's over now, he won't ever go near you again. Neither will anyone else, (Y/N). Because no one deserves to ruin such a beautiful mind." You buried you head in the crook of his neck as he flashed the two of you away. "I love you."

"I love you too."
