Author's Note: In the Earth 13/Earth 2 sections Kara & Alex aren't related as well as in Earth 27 section Kara isn't Kara but Marley Rose. I used some of the plots of Ally McBeal, Arrow, Criminal Minds, Game of Thrones, Halloween, the Flash, Legends of Tomorrow, Merlin the series, Scream, Slasher, Supergirl the movie/TV show, Death of Superman, Superman: Earth One & Vol. 6 of Supergirl. I own nothing.


When Winn visited Barry on his Earth, Earth 1, he explained the multiverse theory to the newest DEO agent; "All right. So imagine there're multiple versions of Earth. . . so all of these Earths occupy the same place in space, but they vibrate at a different frequency so they can't see one another."


On Earth 26, 20 years after the massacre in Haddonfield, Dr. Loomis' former colleague returns home in Langdon, Illinois to find that her house'd been burgled. Her teenage neighbor Jimmy & his friend Tony call the police; she discovers that the file on Michael Myers' sister missing. She immediately rushes back over to Jimmy's house where she finds him & Tony dead. Michael suddenly appears & attacks her before slitting her throat, killing her. The police arrive just as he leaves the house with Cat's file, elsewhere, Cat's living in California with a seemingly perfect life with her teenage son Carter. However, she's far from happy, as the tragic events from '78 still haunt her & lives in fear that her brother may return. She's tried to get her life together with the hope that her psychotic older brother'd never come after her again. The next day she's in a foul mood & it doesn't improve; she spills her coffee on herself & on top of that, she gets a call from her son's school stating that he'd not been in school at all. She's furious. When he finally arrives, she starts in on him. "Out of all the days to pull this shit it'd to be the one day of the year that you're supposed to do as I ask; what the fuck Carter!" He shouts back that "MICHAEL MYERS' DEAD!" After that outburst, he leaves. "Ms. Grant're you all right? I heard his outburst. Do you need anything?" "No Kiera I'm fine; I'm just going to go home to get ready for the annual CATCO Halloween Party." With that, she leaves; a few hours later she arrives &s greeted by her assistant dressed as Supergirl whereas Alex's dressed, as herself but Cat doesn't know that. "& what're you supposed to be?" "I'm a federal agent that works with Supergirl & who're you supposed to be; Brigitte from 'the Pretender'?" "Yes." Then after spending a few hours Cat abruptly leaves for her office; when Kara sees this she goes after the other & when she gets to the balcony she consoles her boss; Cat'd seen an employee dressed as her brother. "What's the matter?" "Let me tell you a story." Then once that's over with Kara looks into her boss' eyes & realizes that she's talking to the sister of infamous serial killer Michael Myers but this doesn't faze her in the least bit but makes her more sympathetic to her boss' plight. "Don't you worry because if & only if he somehow shows up again Ill've my sister take care of him; you don't need to be afraid of this holiday anymore. I promise." "What'd you mean? My son told me he's dead." "No, he isn't. He returned to Haddonfield, tried to kill Tommy Doyle & then disappeared." When she finds this out she starts freaking & tells Kara she needs to go into hiding. However, before she can do that, they hear a voice; it turns out to be Tommy himself. "Don't worry the Mark of Thorn isn't appearing in the sky this year so your safe." Cat rushes up to the young man & gives him a hug. "What're you doing here?" "I'm here for the party." He then explains what he does at CATCO. "Now if you excuse me I must be leaving because my son Danny's in the hospital with Pneumonia."

CATCO Worldwide Media experiences a seismic tremble because the car that Tommy entered exploded from a bomb that's been planted by a Cult of Thorn member then a week later while still grieving over the loss of Tommy Kara appears with a social worker. "Ms. Grant a Mrs. Krueger-Voorhees' here to see you." "Please take a seat." The woman then wastes no time with pleasantries, she just gets to the point, & after that, she asks Danny to join them. "She's going to be taking care of you & Stephen from now on. Mrs. Grant this' your cousin, as well as the other, being your nephew/grandson." With that, the worker leaves. After that she gets confused on the last part so Danny fills her in then once that's over with she excuses herself so she can go use her private bathroom where she ends up breaking down; during that time Kara asks him if he wants/needs anything. "I need Stephen's away bag that's got his food in it." She does as told & after the 3-year-old eats Danny realizes that he needs a diaper change. "Well, I'm going to Noonan's. Do you want to come?" After they leave Cat reemerges & gets back to work then 15 minutes, later Cat hears "Hey Cat here's your coffee & a salad with a cheeseburger on top." "Thanks, Danny; by the way's that what you want to be called?" "You can call me whatever." "Daniel it is then. So that's Stephen?" "Steve this' your aunt? Grandmother?" He then looks back at his cousin as if to ask what she wants the toddler to call her but before she can respond Supergirl shows up. "So these're your relatives?" "Yes. These're my cousin & nephew/grandson. Daniel & Stephen this' Supergirl." Then before the older boy can do anything, much to his surprise, Stephen starts walking on his own towards the Girl of Steel who then picks him up. "Hey there Mr. Man, what's up?" He doesn't respond but instead looks out the window where he spots a man in black looking at him but the Maiden of Might doesn't pay him any mind. She stays for a few minutes but then goes back to work. A few hours later Cat also leaves then a week later, they start school: Stephen goes by his middle name Thomas. Cat then decides to take a sabbatical from her empire for 2 years & during that time, she & Kara become closer then sometime later on Kara's about to take the boys to school when all of a sudden, out of nowhere Cat pulls her in for a kiss. "What's that for?" "For taking care of us." "I'll always take care of you guys; you're my everything." After that admission, Cat grabs Kara's phone to call Alex who ends up being asked to take the boys to school. "Sure also I'd like to use them as an excuse to go trick-or-treating with Mags." With that, SuperCat gets the weekend to themselves; if only for a short time. Later on, they're having rough sex, which's interrupted by a call from the man in black who state's he's got Alex, Maggie & the boys' hostage. The two women then get hurriedly dressed to go save everyone with the help from some DEO agents & surviving Myers victim Lindsay Wallace. They arrive too late to save Daniel who'd ended up getting the Mark of Thorn passed onto him from the man in black who turned out to be Michael himself. "Now I'm free from this curse." "Yes & now you're free to rot in hell." With that, Cat shoots her older brother in the heart/head. After that, she turns to Daniel to plead with him to fight his new nature but to no avail so Lindsay decides to take matters into her own hands. "You cant've Stephen but you can've me." He takes her up on her offer & with that, the curse gets transferred into her but just before her humanity's left her she gets the wherewithal to slit her throat & throws herself off of Cat's personal CATCO balcony thus saving the Grant/Lloyd/Myers/Strode/Zor–El family from its ancient evil. A year later SuperCat gets married, adopt Daniel/Stephen & everyone lives happily ever after.
