You and Wally have been friends for a while, but since you were a siren, he was kinda confused about what's the difference between you two. Expect for how you loved tricking idiot women/men into the deep water with your angelic singing. He never understood how you needed to eat humans to survive since mermaids would just eat Kelp or Seaweed. But it was a normal day of you tricking people into the waters till Wally saw you and swam closer. And saw the gore of the body's and looked at you.
