Adrien, dressed as Cat Noir, was fishing in the pond when suddenly, something caught the bait and he reeled as hard as he cold to not let it escape. And then, once it came out of the water, the fish was revealed to be...
Hawk Moth?
"What are you doing here?" asked Adrien.
"Corrupting fish, of course," answered Hawk Moth in a nonchalant tone.
Adrien got os angry at the response, he literally kicked Hawk Moth into outer space as he yelled "I regret nothing!"
