Okay I think along with Emma Wells cat Noir knows about Ladybug being Marrinette cause he ONLY ever flirts with Ladybug well in the Elivustaor (sorry spelled wrong) episode he was flirting with Marrinette he never flirts with girls only Ladybug he never flirted with Chloe or Lila or anyone so why does he flirt with Marrinette randomly cause he knows that she is Ladybug (or he could have a crush on Marrinette but he could know it goes either way) comment if u agree or disagree and write why
