kara in the current continuity doesn’t really have a secret identity anymore. like, she is working as kara zor-el, she probably signed her rent papers with “kara zor-el” etc. BUT. she also most definitely didn’t disclose she was going by kara danvers at one point. you know, because it would be dangerous for the few people she got close to during rebirth. so by now i’m pretty sure the missing case of kara danvers has gone cold. the people she went to high school with think she is most likely dead. one of them made a tiktok talking about her that blew up. “a girl in my class didn’t come to school one day and we haven’t seen her since. this is her story.” for all we know, there might even be a true crime episode dedicated to the disappearance of kara danvers. i’m sure she is flattered. the neighbours probably still occasionally bring eliza and jeremiah diner once in a while. “i’m sorry this happened to your daughter. she was such a bright kid.”, “we know, it’s just… so sad, man. *supergirl flies over them* just so so sad.” afterwards, they invited kara to eat the food together. they also tell her they should just fake her death at this point. she doesn’t want to. it’s just about the funniest thing that has ever happened to her (of course she tells her friends what really happened. she doesn’t let them be turmoiled by her “death” for too long.)
anyway, i think next time she has an ongoing she should team up with a detective buddy of her who got hired to investigate the strange disappearance of kara danvers. he doesn’t know supergirl went by “kara danvers” at one point. “hey, kara, isn’t it strange you both have the same first name?”, “what can i say, who doesn’t like the name kara?”. they investigate together for a while, because it’s just so funny to kara. but in the end she tells her friend and they finally fake kara danvers’ death.
