Question: does marinette ever find out adrien is cat noir?
Answer: In season 2, the Hawk Moth's identity is revealed as Gabriel Agreste. Also, we see Marinette being taught by tutelage about the Miraculous. ... Marinette/Ladybug doesn't know that Adrien is Cat Noir and at the same time, Adrien is unaware that Marinette is actually Ladybug.
