The 'Does He Know?' meme originates from a scene in the 2022 film 'The Batman,' featuring Paul Dano as the Riddler. The image captures the villain staring intensely at Batman through a glass partition, seemingly questioning whether the caped crusader is aware of a secret truth. It first gained traction on social media and image boards as a reaction image used to mock people who are completely unaware of something obvious or are being trolled without their knowledge. The meme’s power lies in its condescending yet inquisitive tone, making it a staple for internet commentary on ignorance, dramatic irony, and secrets hidden in plain sight.
