Kaia Nieves

"I run. But sometimes they catch me."

- Kaia to Claire Novak

Kaia Nieves was a dreamwalker orphaned as a result of a supernatural tragedy.

History
Kaia lost her family at a young age. By the time she reached adulthood, she was on her own, completely disconnected from her roots, as she tried to understand a burgeoning gift: In her dreams, Kaia walks between worlds — a rare and terrifying power she experiences only as a curse... a power she doesn't understand and can't yet control. Flinty, sarcastic, and profoundly haunted, Kaia is nevertheless strong and willful as hell — she's had to be to survive this long on her own.

Season 13
Kaia was seen in the drug treatment facility and was arguing with the doctor who told her to open up to the other clients. She defended her addiction and walked out and she met Jack who claims to be cocaine addict, much to her confusion. Jack eventually admits that he needs Kaia's help and offers to help Kaia escape in exchange. Subduing a doctor, Jack is able to help Kaia escape through a triple-locked door. However, Kaia refuses to help Jack and runs off after hitting him while he was distracted by the Winchesters catching up to him.

Free again, Kaia wandered the streets and accepted a ride from a man and woman who offered her help. Upon getting in, she was knocked out by the woman as they drove off.

While being held captive, Kaia asked why they took her and learned that she was to be bait for Jack who was the son of Lucifer. Kaia was very surprised by this news though she doubted he would come for her. Dean and Sam soon barge in along with Jack and Kaia was left in awe at his powers as he subdued one of her abductors and killed the other. After this, she is very surprised to learn that Dean and Sam hunt monsters and that her kidnappers were angels. She attempted to walk away from the unbelievable things she heard. Jack tried to stop her but failed. Dean then held her at gunpoint and ordered her into the car.

Along the drive, Kaia was annoyed by her situation and ignored Jack's attempts to apologize and understand her situation. Jack offered to show her other worlds besides the horrible one she has seen and she accepts. She was greatly amazed by the beauty of the other worlds as Jack says she could see more if she helps which she agrees to. While the angels use their powers to try and destroy the warding spells, Kaia attempts to concentrate on the Apocalypse World, the universe where Mary Winchester is in, but she keeps flashing back to the Bad Place that has haunted Kaia all of her life.

Kaia inadvertently sends herself, Jack, Dean and Sam to different places. The glow she and Jack emit as they open the portal together causes the nearby angels to disintegrate into dust. While Kaia is left unconscious on the side of the road, Jack is transported to Mary while Kaia's flashing to the Bad Place results in the Winchesters being sent there instead.

A few days later, the still-unconscious Kaia was found by a man who called an ambulance for her. Kaia was taken to Sioux Falls General Hospital where she was treated for a mild concussion and dehydration. At the same time, Claire Novak was looking for her with the help of Alex who worked as a nursing assistant at the hospital. Alex found Kaia logged into the system as a Jane Doe and directed Claire to Kaia's room. Claire found Kaia as she prepared to bolt and attempted to convince Kaia to help without success. Outside, Kaia was confronted by one of the Cloaked Figures from the Bad Place to her shock, but Claire and Jody Mills killed it.

As Jody, Alex and Patience Turner performed an examination of the creature's body, Kaia sat outside with Claire. Kaia explained to Claire how she saw the creatures in her dreams and they gave her scars. Kaia warned that the creatures ran in packs and once they got someone's scent, they would never stop coming after a person. Kaia and Claire compared scars before Kaia explained about the Bad Place, the creatures and her work with the Winchesters to Jody's group. After Claire realized that the rift to the Bad Place must still be open, Kaia warned that if they went to the Bad Place, they would die.

A short time later, the group was forced to flee the house after Patience predicted that the Cloaked Figures were about to attack. Along with Claire, Kaia watched the attack on the house in horror. After stopping to meet up with Donna Hanscum, Kaia told the group what she knew of where the rift was, allowing them to identify it as the Larsen Bros. Shipyard. Kaia remained behind with Alex, Claire and Patience as Jody and Donna went to search for the rift. As they waited, Kaia comforted Claire over Patience's vision and urged Claire to go after the Winchesters, promising to go with Claire if she did.

After the girls rescue Jody and Donna, Claire and Kaia find the rift which is closing. With more Cloaked Figures coming after them, Claire goes through the rift to the Bad Place accompanied by a scared Kaia. Kaia was able to lead Claire to the Winchesters and the two rescued them, with Kaia informing the Winchesters that she thought Jack was in Apocalypse World with their mother. Upon their return to the rift, a hooded figure appears that threw a spear at Claire. Kaia shoved Claire out of the way and took the spear in the side herself. Dying, Kaia reached out to Claire and held her hand as she died. With a Giant after them, Claire and the Winchesters were forced to retreat through the rift which closed behind them, leaving Kaia's body in the Bad Place.

After Claire and the Winchesters return, Jody comforted Claire over Kaia's death while Patience realized that her vision had actually been of Kaia dying and Jody comforting Claire. The devastated Claire swore revenge on Kaia's killer who managed to make it through to the Main Universe and was revealed to be the alternate reality version of Kaia herself.

Powers and Abilities
Kaia was a very powerful dreamwalker.
 * Dream Walking - While in a state of dreaming, Kaia could see into other worlds. She was mainly focused on the world she called The Bad Place but could change the worlds she looked into. Unlike other dreamwalkers, Kaia's visions of the Bad Place left her with physical scars.
 * Molecular Combustion (combined with Jack) - While combining powers with Jack to open a rift into an alternate reality, Kaia's screams caused her and Jack to emit a yellow glow that disintegrated six nearby angels.
 * Portal Creation (combined with Jack) - While combining powers with Jack, the two displaced themselves and the Winchesters. Due to Kaia flashing between the Bad Place and Apocalypse World, Jack ended up in Apocalypse World, the Winchesters in the Bad Place and Kaia on the side of the road with a rift opening for a few days to the Bad Place.
