You should always have boundaries with other people, especially with the ones you have feelings for.

Sam and Dean Winchester were trying to figure out how to get the mark of Cain off Dean while working on a case about mysterious murders.

At first, they thought it was a Rugaru gone rapid but as they investigated the murder of a sixteen-year-old girl named Janet Madison, the brothers realised something else was doing this.

They go as detectives, named after the rockstars Plant and Paige, to talk to a student who was with her on the night she was murdered.

The student Guti Serenade admitted that Janet had been bullying him.

He then goes on to say that they were out one night in a cemetery because Janet wanted Guti to steal from a person's grave.

He sees that Janet was going too far and is about to tell her that she won't play along but a cloaked figure grabs Janet by her neck and he runs so the person wouldn't catch him.

The next day, he heard that Janet was hit by a bus, horrified because even though the bullying had stopped, Guti didn't want anyone to be killed.

The Winchesters talk about the case in the Impala, now thinking that it could be a vengeful spirit who goes after the ones who threatened other people's family members.

That is until two friends named Richard and Jason were hanging out & making jokes to pass the time when they saw a cloaked person, looking at the bandstand.

Richard goes over, thinking it was a prank that a friend was pulling until he tries to tap their shoulder, only for the figure to turn and grabs Richard by his neck.

Jason goes over to try and free Richard as he got a good look at the figure as she speaks to the boys.

"You two should be careful, otherwise the both of you will be hit in the head with a crowbar."

The figure disappears, letting go of Jason as the two boys were confused about what just happened.

They ran out of the bandstand but see a woman who was wearing clothes as black as ink and golden eyes that had frozen them in place, like an animal to headlights.

The boys thought that she could help her until the woman lifted a crowbar and smacked Richard in the head, instantly killing him, and turned to Jason, who tried to run away from her but was caught and killed just like his best friend.

Sam and Dean talk to Jason's mother, Ink Dye, about the recent murders, telling them that she saw the murderer as she was about to pick up her son and his friend.

She said that it was a red-haired woman who was wearing a leathery mask with a cloak over her head and the other person who had golden eyes, which confused the brothers.

Unfortunately for Ink Dye, the Winchesters see that she was lying.

Just then, a person comes into the room, who turns out to be the mother's best friend, Magpie.

Magpie talks to the false agents about the recent murders and starts to talk about her beloved, Lost.

She talks about how her beloved once told her that Lost would meet an untimely demise by a person closest to Magpie.

She thought it was a joke at first until she heard the news from another friend, who goes by the nickname Scribbler, that she had her head bashed into a brick wall.

Sam asks where Lost was buried but unfortunately, Magpie tells them that she was cremated.

Dean asks why Lost would say something out of thin air and how Mag's answer gave the boys a slight idea of how special Lost is.

"Losty has special gifts. She would always know what kind of person you would be just by a glance & can predict how people would be hurt and sometimes, predict a person's death."

After the two talked to Magpie and Ink, they went to a park in the evening & realized that she was a psychic when she was alive hence why Lost told her beloved about her demise and when she died, she & her psychic powers came back as a spirit or to be more accurate, a Death Omen.

Unlike vengeful spirits who kill because they couldn't move on easily until their body or something with their blood or sweat on an object is burned with salt, Death Omens have another way to be put to rest.

Seek justice for what was put on to them, in this case, Lost wanted to be avenged for her murder and for her beloved to see the truth about her killer.

As the brothers were talking about plans, Lost appears in front of them and points at Dean before asking "Where's my beloved?" and disappears.

Sam then turns to see a woman and tries to fight back until the woman, who reveals herself to be Ink Dye, knocks out both the Winchesters, taking them to her home, tying them up and placing them near a couch.

As they awoke, Ink Dye told them that she would enjoy carving their innards like pigs.

The brothers then put the pieces together and figured out what was going on.

Ink Dye had murdered Lost because her psychic powers showed her what she was: a monster.

In Ink Dye's anger, she growls at the boys and shows her golden eyes which instantly reveals to them that she is a Werewolf, one with a more controlled appetite.

What Sam and Dean don't know is why she was killing other people.

Ink Dye then talks about her envy towards Lost because of the psychic being with Magpie, even admitting that she mainly killed Lost because she was in love with Magpie, or more accurately, obsessed.

Ink Dye then admits to killing people who were family friends or people who even knew Magpie because Ink Dye believes that she is the only one Magpie truly needs.

Sam then asks Ink Dye what if Magpie finds out about her killing Lost.

Ink Dye tells Sam about what she would do if Magpie found out, distracting her enough for Dean to sneakily grab her phone on a chair and texts Mag saying "I found Lost's killer, come over quick!!!" while Sam cuts through the rope with a silver pocket knife.

Sam quickly gets free, slashing Ink Dye's cheek with the knife, and getting Dean free.

Ink Dye easily overpowered the hunters and was about to kill Sam until Dean throws her phone at the back, getting Ink's attention.

Ink chuckles, not noticing the text Dean had sent as the phone powers off, and goes over to the eldest brother putting Sam's knife on his neck.

"Do you think that you could take my love away from me? I will kill you, JUST LIKE I DID TO THAT RED-HAIRED BITCH!!!"

An audible gasp was heard as Ink Dye turns to see Magpie, who was horrified by what she had just heard as she saw Ink's golden eyes.

Ink Dye tries to lie her way out and shift the blame onto Sam and Dean until a voice was heard.

"HEY, PISS EYES!!!"

Everyone in the room turns to see Lost who was giving death glares towards Ink Dye, who terrifyingly steps back and yells at Lost to stay away from her.

Lost goes up to Ink, putting her hands on her murderer's neck, and strangling her.

Ink Dye feels the death omen's hands wrapped around her neck, getting tighter and tighter, letting go of the silver pocket knife.

Sam grabs the pocket knife, stabbing Ink in the heart, instantly killing her.

Lost turns to Mag, reverting to her normal looks before she died.

Mag and Lost go to one other, both of them happy to finally see each other again one last time & kiss as Sam and Dean leave.
