(Damon Salvatore and Caitlin Snow)

Disclaimer: I do not own The Flash or Vampire Diaries.

The story picks up where Damon and Enzo are possessed by evil from the Pandora box. They're lashing out in Mystic Falls, not knowing the damage they've done. No one has found a way to bring them back, to their normal selves. One night when they're on their own killing spree, Damon gets captured by an unexpected line from the Augustine inheritor.

On the other hand, Caitlin Snow decides to leave Central City after a series of tragic events that wounded her deep. She decides to go back to her hometown where her ancestors originated from, Mystic Falls. She accepts her uncle's offer to continue her family legacy. She loses her faith on happiness. Her legacy is what she believes where she might belong all along.

Chapter one

One warm night on Mystic Falls won't be complete without blood spilling on the street leaving reckless trace for the gang to cover again and again. Day thirteen has passed yet no one finds a way to bring Damon and Enzo back from spiraling out of control because of the evils possessing them. They're not their true selves. Even though they can hold themselves sometimes, the evils always get the best out of them in matter of seconds.

Damon lies on the ground near the town line. He has blood stain on his neck, arms and all over his black shirt. On his side is a bottle of red liquid that's actually wine mixed human blood drained from one of his victims that night. He sits up when his vampire hearing catch a sound of car driving towards where he is.

"A newcomer?" Damon tilts his head, seeing a car coming from far away driving towards the town line, Mystic Falls. "Well, more blood, the fresher, the better." He takes a sip from his bottle, enjoying himself and waiting for that car to cross the town line. He crosses his legs and sits facing the town line. His lips are forming into a smirk as the car is getting closer to Mystic Falls.

While Damon is waiting, the woman who's the one driving the car to Mystic Falls, isn't really aware since her mind is still back on her city and the people that she left, the ones she cares about. The decision to leave is a big move for her, a life changing decision. She lets out a heavy sigh while closing her eyes for a second.

"No!" opening her eyes to a view right in front of her, she's shocked and hits the brake in a heartbeat and has no time to turn the wheel. But that guy sitting on the street doesn't blink as her car makes a sudden brake. She closes her eyes, her hands holds the wheel so tight, knowing for sure she'd likely to hit whoever is on her way.

Her heart races as if it's going to jump out of her chest. Her hands are sweating. She felt that her front car hit whoever it was. She's calming herself before she comes out of the car to check on the one she just hit. She's shaking and worried that she might have hit him hard. She can't get in trouble right now, not in her first second coming to the city.

Her eyes go wide, knowing no one is there. She walks closer to the front of the car and look for a sign. Caitlin furrows her eyebrows upon finding a bump on one side of the bumper. She lets out a sigh. As she looks up, a guy suddenly standing so close to her shocks her to death.

"Aaah!" her heartbeat skips a notch. "How?"

"Hello, there." He shows his typical Damon smirk. Tempting. He's so close to her face. His lips are mere inches from hers. He enjoys feeling the breathe she takes in and out.

Caitlin pulls herself back a little. "How did you do that? You got hit. Are you speedster? You're healing and you move so fast." She starts checking on his body.

"What's speedster? Is that a joke?" Damon snorts and looks offended.

Caitlin is still busy checking on him. She gasps. "You got blood on your neck and oh your shirt! I'm a doctor, I can patch you up. Even speedster needs some medical attention."

Damon sighs. "Stop with the speedster joke, doctor. I'm way better than speedster. I'm healing perfectly and I can whoosh smoothly." He looks at her again, closely and suddenly he realizes her. "Caitlin? Snow?"

Caitlin stops in a second just as she's about to open the car. "Did you just say Caitlin Snow?"

Damon tilts his head and adds a wink. "Wait, do you hear that?" he suddenly catches Caitlin's hand. With his vampire hearing, he can catch a suspicious ticking sound from inside her car.

"What?" Caitlin tries to free herself from his hand.

Damon doesn't listen to her. His hearing is on something suspicious. He looks like he's wondering. In a matter of second he takes Caitlin with him in one whoosh away from the car, exactly a second before the car suddenly blows up.

"Bam! See? Someone is after you Doctor Snow." Damon drinks from his bottle that he saved along with him from the blow.

Caitlin drops her jaw open. She looks shocked and terrified and confused to what just happened. Her car just blew up in front of her. She almost died if not for Damon saving her. She's had enough heart attacks in one night, just less than hour she came in this city. She can't imagine what her life would be in Mystic Falls.

"No one is after me. How could anyone be? I'm new in this town." She pushes Damon whose arm still hangs around her waist. "And how did you know my name?"

Damon just pouts and looks at her murmuring while he's drinking her wine-blood. Caitlin yelps when he throws the bottle to the car in fire after he finishes it. She finds her right arm is bleeding.

"You're welcome, Dr. Snow. Go patch yourself up." Damon shows a smile that's slightly crooked. As the wind breezes, Damon snaps. The blood that he drank and the smell of blood from Caitlin's fresh wound is a trigger. He grunts. "Not now!"

Damon snatches Caitlin in a snap bringing her across the street. His eyes are getting darker. The Pandora evil is trying to get a hold of him. Caitlin closes her eyes when Damon sniffs her cheek and to her neck. He looks like trying to control of himself instead of the evil controlling him. But the evil is too dark.

Caitlin tries to get away from him but Damon is holding her so tight. His hands almost crush her arms. She whispers. "Whoever you are, I believe you don't want to hurt me. You just saved my life."

Damon's breathe is getting heavier. He might not be able to hold it any longer. Yet the urge to sink in his teeth into her neck is irresistible. "I told you to go, Caitlin! Why do you even come back now? Mystic Falls will be the death of you and I'll be the one who makes sure of it." He says that as his open mouth is ready on Caitlin's neck.

"Nooo!" Caitlin cries but instead of feeling some a pain she hears Damon screams in pain just right a second after she cries. Two arrows shot through Damon's leg and waist. He falls on his knees, feeling all of his strength is absorbed. Damon tries to stand on his feet again. He's still holding on Caitlin when he's slowly falling. And in few seconds, he's completely weak and falls on Caitlin's arms.

Ten feet from her she eventually sees a guy walking towards her. "Welcome to Mystic Falls, Caitlin."

"Uncle Greg!" she stumbles because Damon is weighing on her then she falls on her butts along with unconscious Damon on her lap. She cringes.

Greg only gives a slight smile. "Sorry you have to meet your first subject this way."

Caitlin gives questioning look. Her forehead is wrinkled. She gets rid of Damon and lays him on her side.

"He is your first test subject. Damon Salvatore, the evil vampire who's roamed Mystic Falls."

Caitlin is completely clueless. "A vampire? Why no one told me about this before?" she didn't know a thing about her legacy or that legacy deals with some supernatural beings.

Greg throws Damon on his shoulder. "Come on, it's not safe for you to wander alone at this hour."

"He, Damon just saved me." Caitlin stands up and tries not to feel the pain on her arm. "My car blew up."

"It must be his play. Damon has his own way. You can't trust anyone here, Caitlin. And Damon would be the last person you can ever trust. Note my words." Greg is so serious about his warning.

Caitlin just nods. She doesn't think Damon did that. She just believes Damon from the way he knows her name and throws tantrum at her that there's a little care in it. It doesn't add up. Nothing makes sense for her, yet. She has to get used to it since this is her life now. Mystic falls is where she'll have a fresh start. Damon Salvatore is her first subject that has become a mystery for her to solve.

Chapter two

"Tick tock tick tock. Hhmm, 4 letters down, white and cold." Damon raises his voice for Caitlin to hear what he's mumbling. "You have any idea what that is?"

Caitlin, who's sitting on her desk, turns to left and just gives him side eye. "Can you stop mumbling? I like you better when you were unconscious."

"I'm creating an imaginary crossword in my mind. Four words down, white and cold. Come on, Doctor! You're supposed to keep me entertained while you're restraining me on this goddamn cell." When Damon touches the tip of the finger to the cell, it burns him, yet he plays with it because that's how bored he is.

Caitlin lets out a heavy sigh. She's scanning over the journals that her uncle gave her to learn more about her family legacy and what her role as inheritor of the legacy that she'd never expect.

"Aha! It's S – N – O – W." Damon yells. "Four words, white and cold. Yup Snow."

Caitlin feels annoyed and responds to Damon by pretending like she's reading something from the journal out loud. "Salvatore. Damon Salvatore. A vampire, worst of the worst. Merciless and savage evil. Oh, a jerk. This is interesting."

Damon responds. "Blah, blah, blah." Now he's
