When the newest agent sees the Girl of Steel she becomes frightened because she's reminded of when cyborg Superman attacked her a few years ago so Lillian'd be able to get her blood so Lex's storage facility'd be able to get opened so that she'd be able to use the technology for the organizations that she's affiliated with. Kara sees the fear in the other woman's eyes so she decides to make the other more at ease by asking Alex to put on the kryptonite emitters on high so that she's powerless. Alex asks her why she'd want to do that, Kara just stares at Lena & Alex follows her gaze. When she sees the other shaking, she does as Kara asked. After that, Kara gets on the med bay bed so Lena can do her thing. After the examination, Lena tells J'onn & Alex that Kara's infused with Nth metal that makes her more impervious to all types of harm. After that, Kara asks to speak to Lena alone but before she's able to do that Cat ends up coming into the room & rushes into Kara's arms. She asks if it's her to which Kara just nods, Cat asks if she'd be able to leave the DEO & let her come to CATCO & they tell her that she can do that. While walking away, while she's holding Cat's hand Kara turns her head & locks eyes with Lena until the youngest Luthor's out of sight. After that, over the next few months, every time Kara closes her eyes Lena's kyptonesian green 1s stare back at her, meanwhile, Lena's been having dreams about Supergirl as well but not all of them're pleasant. Sometime later Lena's best friend Jess notices that she seems to've a faraway look more often than not & today's no different.
She asks if Lena's okay, Lena tells Jess that she's fine & that she's just a little tired to which the other asks if she'd another dream. Lena nods her head yes & a tear escapes her eye. Jess comes over to hug the other & to wipe her tears. Just before they're about to pull away the door opens to reveal Alex & Kara. Jess decides to take matters into her own hands by asking Alex if it'd be able to speak to her about the plans to work with her company because there're some things they need to iron out in the details; she's sure Lena can keep Kara company. With that, Jess leads Alex out of the lab before she's able to say anything. Once they leave Kara moves towards Lena who ends up shuffling backward. Kara catches her but they end up still falling backward but Kara makes it so that Lena falls on top of her & not the other way around. Lena thinks that when Kara falls on her she'll freak out; when she sees Kara making sure that Lena falls on top of her. When this happens she freaks out less & less. After falling to the ground, Kara stays still for Lena's benefit. Lena ends up exploring Kara's face with fleeting touches. Kara does something she hadn't in a full decade; she lets a human hand touch the cyborg portion of her face & after a while, she fully leans into Lena's warm hand. A little while later, they both get up from the floor whereupon Lena states that she's got some things for her; a blue-colored laser to replace the red 1 in her eye as well as a skin glove for Kara's metal hand so she won't frighten people so much. Kara states that Lena means that she won't frighten her so much, that she can keep them because Kara doesn't need them, that Lena can keep them because Kara doesn't need them, that she just wants to be accepted the way that she is & Kara starts throwing things all around the room, which causes Lena to flee, she ends up running into the room that Alex's at, tells the other what'd happened & with that Alex goes rushing to the fallen Kryptonian. When she gets to the other, it breaks everyone's heart at the sight of Kara rocking back & forth, crying & repeating that she just wants to be her; this causes a light bulb to go off in Lena's head; that she needs to contact her other friend Sara Lance because they can use the Lazarus pit. Lena explains to everyone what that does & that they'll make Kara the way she'd used to be. Alex states that it only prolongs life by making a person younger. Lena states that it also'd be able to get rid of the cyborg person of her because that part's 'dead' so to speak. A few days after this that's exactly what happens but what they don't realize's that Talia's reconciled with her father & that the League of Assassins' partnered up with the other evil organizations to get Superbird back until they're captured & brought to an undisclosed location; Kara groggily wakes up in a dark place very scared. She wakes up to ask Lena where they're at & Lena states that she doesn't know but that she's got an idea. As soon as she says that, a disembodied voice says welcome to CADMUS & after that Talia al Ghul, Lillian Luthor & Maria Powers step out of the shadows. When Lillian sees her daughter, she starts freaking out. They explain that she'd been brought in with Kara to whom Lillian tells them to get Lena out of there. They try to do that but Lena stands her ground so they roughly take her out & Lillian asks Talia to please teach Lena a lesson. The other does as told. A few hours later Lena got put back in the cage where she waits for Kara to return & when the Girl of Steel does, she's in a sleep state. Lena tries to wake her up but it doesn't work. She's so wrapped up in doing this that she doesn't realize someone else's in the room with them until the disembodied voice speaks telling her that the Talons're a breed of deadly assassins that're loyal to the Court of Owls. They remain 'sleeping' deep within their inner sanctum until they're 'called' upon. The Court, seemingly obsessed with Greek mythology, began using electrum, a highly conductive alloy of silver/gold with trace amounts of copper & other elements, to treat their 'retired' Talons. A serum's eventually developed that coupled with the electrum'd bring the dead Talons back to life. Talons so revived appear to be unkillable, surviving knives through the skull, electrocution, losing a body part, falling from the height of a skyscraper, etc. If exposed to extreme cold the revived Talons'll shut down, entering a kind of stasis. The only means verified to kill a revived Talon's a poison developed by the Court; the Talons're highly trained/conditioned.
They're extremely proficient with knives & experts in hand-to-hand combat. Talons're to follow the Court's orders & serve until they're deemed unfit for service due to age or failure, at which point they face their chosen successor. This' spoken by fellow Talon Uriah Boone & after other Talons show up. Once Lena sees all of them, she backs up into a corner to try to get away from them but they enter the cell anyways & tell her it's time for them to bring her back to where she came from. She states that she's not leaving Kara but they tell her she's got no choice. With that, they take her out of the cell, chloroform her & dumps her outside the DEO; when she wakes up Alex asks her what happened & Lena tells her that they got taken but she doesn't remember by whom & that Kara's not with her. A few days later Kara returns as if nothing happened. Lena tries to jog her memory but the others not've anything. They state that they're not talking about that & its final. With that, Kara storms out. A few days after that Talon Calvin Rose shows up to aid in trying to bring Kara back to the DEOs side. They ask him why he's doing this & he tells them that he's tired of working for the wrong side & that being evil gets him nowhere. They become suspicious of him so he willingly lets J'onn read his mind & J'onn finds no deceit. After that, he tells them that Lena'd been turned superhuman because CADMUS needed someone to destroy Kara if & when she decided to no longer work for the other evil organizations but thinks they can use that to their advantage. Instead of trying to get rid of her permanently they just get rid of her ability from being the newest Talon. They state 'Once a Talon, always a Talon.' Winn states that they'll just've found a way to do that & also before he forgot he got a SuperSuit for Lena. With that, he produces Terry McGinnis' Batman Beyond suit but Winn ends up beating him to the punch explaining the suit whereupon Talon Calvin Rose becomes very impressed by the other & decides that sometime shortly he'd like to pick Winn's brains about other things meanwhile Lena's relaxing when she sees movement on her patio so she decides to investigate. She comes across Kara who asks to be let in. Lena becomes leery of the woman because she knows that Kara's now a Talon but makes it seem like that doesn't bother her; Kara states that she couldn't sleep & she's wondering if Lena'd like to watch a movie or 2. The other states that she'd love to; Kara picks Deep Blue Sea to which the other asks what it's about. Kara goes on to explain & with that, they get on the couch to watch it but as soon as a shark attack happens Lena blocks her eyes because it scares her.
Kara states not real but even if it's she'd protect Lena who asks to do something else. Kara suggests that they play Settlers of Catan & the other agrees. A few weeks after that the DEO's finally able to get Kara back how she'd been before, Kara asks Lena to be her girlfriend & the other says yes. 5 years later, they get married & live happily ever after but that only lasts for a little because every single Earth got wiped out. God decides to remake all of the 53 Earth but some of them stay the same & this starts when Winn visited Barry on his Earth, Earth 1, he explained the multiverse theory to the newest DEO agent. Meanwhile, 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 teen 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 & live 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. After that, he shouts back that Michael's dead. After that outburst, he leaves. Kara asks her if she's okay but she just leaves to get ready for the annual CATCO Halloween party. A few hours later, she dressed as Brigette from 'the Pretender' arrives &'s greeted by her assistant dressed as Supergirl whereas Alex's dressed as herself. Later, after spending a few hours there, 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. She tells her story. Once that's over, Kara looks into her boss' eyes & realizes that she's talking to the sister of infamous serial killer Michael Myers but this doesn't phase her in the least bit but makes her more sympathetic to her boss' plight.
Kara states that Michael returned to Haddonfield, tried to kill Tommy Doyle & 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. He explains that the Mark of Thorn won't be appearing in the sky this year so she's safe. Cat rushes up to the young man, hugs him & asks him what he's doing here so he explains what he does; he leaves. 5 minutes later CATCO experiences a seismic tremble; the car that he'd entered exploded from a bomb that's been planted by the Cult of Thorn. A week later while still grieving over the loss of Tommy Kara appears with a social worker & the woman just gets to the point & after that, she asks Danny to join them. He gets introduced to Cat who turns out to be his cousin as well as the other boy being her nephew/grandson. With that, the worker leaves. After that, Cat gets confused about the last part so Danny fills her in. 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. He tells her what he needs & she gets it. She asks him if he wants to eat & he goes with her meanwhile after they leave Cat reemerges & gets back to work. 15 minutes later Cat gets her coffee & a salad with a cheeseburger on top from Danny She thanks him & asks what he wants to be called & he tells her she can call him whatever; she decides to call him Daniel. Before she can decide what to call Stephen Supergirl shows up & she gets introduced to them. Before the older boy can do anything, much to his surprise, Stephen starts walking on his own towards the Girl of Steel who picks him 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 & goes back to work. A few hours later Cat also leaves. A week later, they start school. Cat decides to call Stephen by his middle name of Thomas & also decides to take a sabbatical from her empire for 2 years & during that time, she & Kara become closer. Sometime Later Kara's about to take the boys to school when all of a sudden, out of nowhere Cat pulls her in for a kiss. Cat tells her that's for taking care of them to which Kara states that she'll always take care of them; that Cat's her everything. After that admission, Cat grabs Kara's phone to call Alex who gets asked to take the boys to school. She also tells Cat that she'd like to use them as an excuse to go trick-or-treating Maggie & with that SuperCat gets the weekend to themselves; if only for a short time. Sometime Later, 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 whereupon the women 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. Cat shoots him in the heart/head. After that, she turns to Daniel to plead with him to fight his new nature but to no avail. Lindsay decides to take matters into her own hands by getting the curse 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, adopts Daniel/Stephen & everyone lives happily ever after. Elsewhere, on Earth 47, a mission goes awry which makes Superman & Supergirl switch bodies for the rest of their lives. On Earth 48 Kara commits suicide after she couldn't save Alex's plane from blowing up. On Earth 49, Kara takes over for Faith the Vampire Slayer & helps stop the Hellmouth once & for all. On Earth 50 Kara arrives on time to take care of Clark like she'd been supposed to.
