Lafayette Beauchamp comes from an extremely wealthy family from which he is almost entirely estranged. Lafayette is so incorrigible in his vices that he was on his third stint in rehab for drug abuse and alcoholism during his early twenties. Lafayette was placed in a rehabilitation program that was run by a woman named Marie Devereaux. Lafayette was admitted on an outpatient basis on the condition that he is monitored by a British nurse named Amelia Lexington. Very hostile and ill-natured about this arrangement, Lafayette has a constantly copping attitude and makes snippy remarks, even in moments in which his redeeming sides were shown. In his redeeming moments, Lafayette was shown that he'll take up for those whom he considers his friends, such as Amelia.
Lafayette was well on his way towards recovery, however after and incident where he became aware of his brothers death, he slipped into a state of sever depression. Subsequently, after the funeral, he gets strung out on heroin. While intoxicated, he is involved in a fatal hit and run which kills a six-year-old girl named Angelique. Lafayette eventually wakes up and remembers the horrific incident that happened the previous night. He tries to commit suicide by climbing in a tub of water and slits his wrist. Amelia finds him just in the nick of time to rush him over to the hospital.
After his recovery, Lafayette is eventually arrested for vehicular homicide after confessing to the hit-and-run. However, his parents quickly bail him out of jail and enroll him in the same rehabilitation program, however, he is monitored by a different nurse named Estelle. Lafayette was immediately attracted to Estelle and freely expressed himself towards her. The two established a secret affair, however, after Lafayette's parents found out about the relationship, they gave enough money for Estelle to the United States and have an abortion. Estelle did leave France, but she didn't abort her daughter.
During autumn, three months later, Lafayette had fully recovered and had moved to the United States to practice law on the east coast. It was there that he found Celeste on the door to his apartment during the middle of the night. After much consideration, Lafayette decided to ultimately keep his daughter and named her Celeste Helen Estelle Beauchamp (Helen after the girl he murdered and Estelle after his former lover).
Celeste grew up extremely privileged and content with much of her childhood. However, after her father married a woman named Valentine DiLaurentis, her life changed drastically. Celeste was ultimately condemned by her new step-mother as being reckless and defiant. She ultimately had to compete with Valentine for love and affection from her father.
While maintaining her perfect composure on the outside, Celeste had internal conflict much of her youth as a child. At the age of six, Celeste didn't think much about the women or flamboyant men his father was bringing home whenever Valentine was gone on expensive ventures to foreign countries. They were always nice to her. Some of them looked shocked to see that Lafayette even had a daughter. But later in her life she realized that the women and men that Lafayette brought home were escorts or even prostitutes after she walked in on her father being intimate with one of the woman.
As soon as Celeste turned eight, she discovered another secret about her family. She caught Parait, her stepbrother, smoking and selling cannabis. She threatened to tell Valentine if he didn't stop, but he continued, and she never had the courage to tell her stepmother the situation at hand. Two years later when Celeste was ten, Parait died of overdosing.
Early on during her childhood, she gained wanted and unwanted attention from older boys and men. At the age of twelve, she became involved in an abusive, sexual relationship with a senior who was enrolled in a local high school. Celeste made the mistake of inviting him over to her house when her parents were away for the weekend. That night, him and a group of his friends sexually assaulted her. Some of them even recorded the whole incident. After struggling for several hours, she somehow managed to liberate herself from her rapist grasp and obtain possession of a fire iron nearby. Celeste was enraged and screamed at the boys as she swung the fire iron feriously. She managed to injure one boy by breaking his rib and the murdered another one by hitting him in the back of the head forcefully. The rapist ran out of the house and Celeste plopped on the floor nude sitting in a fetal position throughout the night. Celeste looked at the inanimate, lifeless body decorated the white-tiled floor of her house. She grabbed her clothes put the body in a bag heading out towards the woods during the middle of the night. It took her several hours, but she buried the body twenty feet beneath the ground.
Celeste locked herself up for a year completely disturbed about the situation that has occurred. However, after Valentine decided that she filed for a divorce and demanded full custody of her two children she had with Lafayette. Lafayette throws a violent tantrum and drives off in an attempt to abscond the situation. In the morning, it is found out that Celeste's father drove off a road and crashed into a ditch and was pronounced dead.
Celeste who overheard the conversation between the policeman and Valentine was appalled. After much consideration, she locked the door to her room and filled her tub with water. Someone was banging on her door, but she ignored them. She slowly climbed into the tub and started slitting her wrist with a razor. She was soon surrounded in a pool of her own blood. She wept as she slowly lost consciousness, before she blacked out, the door to her room burst open and a tall, dark-headed figure loomed over her with a ghastly look on his face.
As soon as Celeste regained consciousness, she noticed images passed by her. She sat up in the front seat of the car next to the dark-headed figure that appeared at her side. He smiled warmly at her and explained to her what was happening. He was a son of Hecate, goddess of magic, who was recruited to help bring demigods to a place called Camp-Half Blood on Long Island, New York. He informed Celeste that she was a daughter of a Greek god, but he didn't know which one.
"You're pretty lucky I showed up as soon as I did. Otherwise, things would be looking pretty dismal..." He said as his voice trailed off. "Can I ask why you did that?"
After minutes of silence, Celeste looked at him with tears in her eyes and told of how she was molested and raped and how her father had died in a car accident. Surprisingly, the son of Hecate knew about Lafayette. He clarified that he was heading towards Celeste, but was attacked by a monster. While they battled, the monster slammed onto the side of Lafayette's car.
"How did you know it was him?" She asked.
"You don't need to know." He replied. (If you're wondering, Lafayette had cheated on Valentine with the son of Hecate's father for a number of years. They both were introduced to each other so often that the son of Hecate thought that Lafayette and his father were close friends).
Celeste had mixed feelings about going to this so called 'sanctuary' in Long Island. She was happy and content to leave her past behind her, but was hundred percent buying what the driver was telling her. After a couple of hours, Celeste encounters her first monster. The car flips and lands on its back. Celeste and the driver rush out of the car to find a Hellhound growling at the two demigods with a ferocious gleam in its eye. As soon as the son of Hecate pulled out a wooden rod that looked like a wand, Celeste put out her hand and a shockwave of energy erupted from the palms of her hands. It stunned the monster instantaneously. The child of Hecate emitted fire from the tip of his wand, and soon the monster fell to green ashes. After the son of Hecate fixed the car with his magic, the two drove off to Camp Half Blood and Celeste was claimed. (Celeste was 13 when she was attacked by the monster, but arrived at Camp two days after the attack on her 14th birthday).
