Angsty Surviving Twins in Live-Action TV series.
- Adam Chandler on All My Children was this after both times his twin brother and Morality Pet Stuart was presumed dead, promptly engaging in self-destructive behavior that nearly ended his life as well.
- This is Justine's prime motivation in Angel. Her twin sister Julia was killed by vampires.
- Lily experienced this on As the World Turns after twin sister Rose was fatally poisoned, going so far as to assume Rose's identity in an effort to keep her alive.
- An episode of Baywatch featured one of these, a woman who would act as both her gorgeous, glamorous sister Maddie and her "plain" sister Gwen. (Maddie drowned when the two were little girls and the guilt-ridden Gwen not only assumed her identity in order to cope, she constantly verbally abused herself as punishment)
- Surviving twin Stephanie "Steffy" Forrester onThe Bold and the Beautiful grown to become angsty. She dated her dead twin sister Phoebe's incestuous boyfriend Rick (who caused the car accident that killed Phoebe) and now for some reason she is going after Rick's mom, Brooke and her family the Logan's. Possibly because of Phoebe's death, though the show fails to recognize it.
- To add to this trope, Steffy is now going after married man Bill "Dollar Bill" Spencer, who is married to Brooke's sister, Katie.
- Played for laughs in Crazy Ex-Girlfriend, in which Rebecca casually mentions in passing that one of the reasons she's lonely at Thanksgiving is that "My dad bailed, my mom's a misery, I ate my twin in the womb."Paula: (horrified) You ate your twin?
Rebecca: (rolls eyes) I mean, medically speaking, I didn't "eat" it. I just metabolised its body parts for my own use. - Played with on Dark Angel. Jensen Ackles's Season 2 character Alec only appeared after his Season 1 character Ben was killed off, and the twins were Separated at Birth, so they never met, but Ben's existence certainly provided Alec with angst. First of all, all the twins of the '09 escapees from Project Manticore were put through the worst of it when Manticore tightened the reins following the escape. And then in Alec's case in particular, Ben being a Serial Killer didn't help things - getting him put in psychological observation at Manticore for six months and later arrested in Seattle for a murder Ben committed. Alec also got a more regretful view of Ben after hearing from Max how he Used to Be a Sweet Kid and she'd had to Mercy Kill him, though he was mostly comforting Max in her angst.
- Played straight for at least an episode after Joshua's brother Isaac died.
- Doctor Who: After "The Day of the Doctor", Osgood and the Zygon who took her shape grow closer and almost become The Dividual, refusing to tell anyone which one is which. They see themselves as the embodiment of the human-Zygon peace. So, when Missy murders one of them in "Death in Heaven", the other is shown to be utterly devastated, and still refuses to reveal whether she's a human or a Zygon. This is demonstrated by the surviving Osgood's attitude. While she still fawns over the Doctor, she's now much more confident in her own abilities and has a hardness to her. She softens a little again, after Bonnie becomes the second Osgood to maintain the peace.
- Farscape: The death of Talyn!John is very much played this way. The immediate expectation is that Moya!John would shrug it off pretty easily, especially since neither Crichton wanted the other around in the first place. To be fair, though, most of the surviving John's angst was because Aeryn wouldn't let him get close to her due to her angst over Talyn!Crichton's death.
- A variation in Finding Carter — the eponymous Carter is alive but was kidnapped as a toddler, and ever since then, her twin sister Taylor had lived in fear of the same thing happening to her (and while Carter's post-abduction life was actually pretty decent, Taylor had no way of knowing that; for all she knew, her sister had met a horrible fate, and Taylor's fears were along the lines of that hypothetical). It's eventually revealed that she has memories of watching her sister be abducted, which probably fueled this further.
- Mark Gray from The Following. He and his identical twin brother Luke were a Serial Killer team until Luke and their mother were killed at the end of Season 2. As Mark is a Psychopathic Manchild who relied on his smarter and more dominant brother to function he loses it trying to recreate him. He dresses a mannequin in identical clothes to himself and taped a mirror to it's face so he can pretend he's talking to his brother and eventually recreates Luke as an alternate personality.
- Cami from The Originals moved to New Orleans prior to the pilot to research on the death of her twin brother Sean, who massacred everyone on the church he worked for before commiting suicide (later revealed to be because he was hypnotized into doing that by Agnes).
- Riverdale begins with Cheryl and Jason, two very close Half Identical Twins. While out on a boat ride, Jason goes mysteriously missing. Cheryl is assumed to have killed Jason. This is later debunked; Jason tried to fake his death and run away from Riverdale, but somehow he really was killed. At first, it seems like Cheryl is faking her sadness over Jason's death. A few episodes in, the fact that her brother - who she believes was her soul mate - has died really hits Cheryl. It goes downhill from there, cultivating in her attempting suicide in the first season finale.
- It also creates some angst for Cheryl to learn that, supposedly, she and Jason were actually triplets, with their brother Julian having been absorbed by Cheryl in the womb and their mother keeping a Creepy Doll of him around afterwards, although it's later suggested this was just a lie or delusion. When the characters are all warped to an alternate timeline where it's 1955 in Season 7, however, Cheryl's twin is Julian instead of Jason.
- The Sopranos: Patsy Parisi angsts about the death of his twin brother Philly often enough to make the rest of the cast frustrated, and when he finds out that Tony had his brother killed for trash-talking him, Patsy gets drunk and pees in Tony's pool (after seriously contemplating killing Tony in revenge). One interpretation of the end of the series is that he eventually went through with that last part.
- The Star Trek: Deep Space Nine episode "Vortex" featured a pair of twins from a species in which twins are always born with a telepathic link. One twin died. The other twin went mad for revenge.
- The species in question are the Miradorn, who also appear in the novel continuity - one story in the Starfleet Corps of Engineers series is set on their home world. This story features another angsty surviving twin.
- WandaVision continues Wanda's status as this. In the present day, Monica bringing up Pietro's death prompts Wanda to kick her out of the Hex. A flashback in the eighth episode set shortly after Pietro died shows Vision connecting with Wanda by getting her to open up to him.Vision: Wanda, I don't presume to know what you're feeling. But I would like to know, should you wish to tell me, should that be of some...comfort to you?
Wanda Maximoff: What makes you think that talking about it would bring me comfort?
Vision: Oh, see, I read that-
Wanda Maximoff: The only thing that would bring me comfort is seeing him again.
[Vision falls silent, glancing at Wanda and visibly unsure of what to say next]
Wanda Maximoff: [softly] I'm sorry. I'm so tired. [Wanda wipes tears from her eyes] It's... it's just like this wave washing over me, again and again. It knocks me down, and when I try to stand up, it just comes for me again. And I can't... It's just gonna drown me.
