Legends of Tomorrow may have been a beautiful garbage fire, but they really had something with Zari 2.0.
You become an overnight childhood celebrity, create an influencer business that makes you and your family incredibly wealthy. Your loser, stoner, brother (that's always had issues with you) brings you to join his group of weird time travelling superhero friends. But there's a catch.
They've all befriended and fallen in love with an alternate version of you. They are constantly disappointed and unimpressed with you, wishing you were someone else.
So you use an ancient magical heirloom to meditate and connect with this alternate you, a version of you that you can never be. And what do you find? She's everything they say about her and more, you talk and connect with yourself on a deeper level than anyone else possibly could. She talks about her brother, someone you never knew, the love she felt for him, the pain of losing him. You talk about your brother, the one she so desperately wanted to save. You find a version of yourself that was willing, not just to die, but to erase herself from existence to save her brother. She couldn't bear to live in a world without her brother, and you realise that you're the same. For all your arguing and fighting, you also love your brother. So you come back to the real world with a new found love of your brother, only to find that while you were gone he was killed. Your relationship, that was just starting to heal, is gone. The alternate you that erased herself for him was wasted, it didn't work. He died all the same.
So you sit there, next to his lifeless body and just sit there, you don't move. The others pick him up and prepare him for a funeral and you sit there.
