"Okay so how old are you?" Dipper asked.
Bill swam around in circles and replied. "No idea think I was born in the 16th century if im not mistaken." Bill said.
Dipper looked shocked.
"500 years ago..." Dipper said speechless.
"Yes Pinetree good boy, you can count what 5 centuries is im so fucking proud" Bill sarcastically mocked. Dipper rolled his eyes.
"Um did you kill any of those-"
"No I didn't kill any of those men, they all killed themselves so I just ate them because free food." Bill shrugged before swimming in circles again.
"We heard you sing!" Gideon yelled.
"Yeah I sang to make them not kill themselves I try at least once to warn them off but I get bored of singing so...I stopped and then I get a free buffet land right next to me."
"When was the last time you killed someone on purpose?" Dipper asked curiously.
"Like around 300 years ago, I was hungry and my mom went missing and well I saw this super cute guy right and then I sang, lured him in, maybe or maybe not made out a little and ate his face, literally." Bill smirked. Dipper went red and was a little jealous, Bill sensed this.
"Why didn't you eat me then?"
"I love you, I never loved that kid." Bill shot back.
"Your mom went missing?" Wendy asked. Bill slouched down a little. He didn't like to talk about it.
"Yeah, she went missing around the time when the depth killers were around...its obvious what happened." Bill's ears fell back and he made a small whine sound.
"Aw" Mabel cooed at the sirens sadness.
"I told you those were a real cult Dipper!" Pacifica yelled at the brunette.
"Yeah yeah, Bill have you killed anyone related to those members of that group."
"Yes."
"So you did kill some of those men?" Dipper asked.
"Yes...??? Okay fine I did but I knew for definite they had history with them because of Steel!" Bill cursed.
"Steel? Wait Mr Steel what does he have to do with it?" Wendy asked.
"Hes apart of the new Depth killer group, he was the one throwing men to their death to lure me in and capture me or any other siren." Bill explained.
"Thats why you killed them?" Dipper muttered.
"I killed his men, his henchmen, his slaves to do his dirty work, they tasted like shit anyways." Bill scoffed. "You cant expect to walk into someones territory expecting to hunt them and to come out alive can you?" Bill asked.
"No."
"Thought so." Bill replied with a humming noise.
"Why did you become human and live with me?" Dipper asked curiously.
"One because I cant go round like this with Steel trying to hunt me can I? Two humans always made me curious so why not and Three Its common to live with your mate." Bill said looking up at the sky.
"M-Mate?" Dipper stuttered.
"Yeah, thats what you are right?" Bill asked unsure. "Your my significant other and you normally settle down with them start a family and blah blah blah..." The siren said.
"Why Dipper why not a other siren???" Mabel asked.
"There are not male and female sirens, just female and half female." Bill said.
