i mean i know you’re intending to make this funny but speaking as someone who absolutely should know a language and have that accent down pat and is their heritage and is horrible at it–it’s really not that funny
and it’s even worse for Clark, because these are the people who are supposed to be his family, the people he was supposed to grow up with and they’re just so alien to him–kara downplays a lot of it since she was told constantly to fit in, and he didnt see her that much but now he’s with his own people and he’s standing out like a sore thumb–his accent, his manner, how he holds himself, idioms that he just doesnt get, references that go over his head, he’s supposed to belong and he doesn’t, and we see in Myriad that Clark thinks like a human
these are supposed to be his people, and even among them he’s an outsider. and it’s another way that kara and clark are alike because at this point–kara’s not really fully one of them either. she’s gone through too much, experienced things that none of them ever had to, not even close–she was the last, more so than even clark, she had to live with feeling like she failed her parents, with being an orphan and growing up in a strange and foreign planet and all that entailed, had to constantly hide and protect
they’re good and kind and wonderful but they don’t belong. not really. not really anywhere tbh–but that’s what it means to be a child of two worlds
