Welcome to my first entry hehe :)

So i personally think that Malikai's daughter is either Avens mom, Aven, or Marissa (or that shes affilliated), and heres why:

Avens mom: She left Aven very abruptly when it seemed she was going to leave and take her daughters with her, she would dye her hair and Aven hair, possibly to disguise them, Harry mentioned that Aven's mom didnt leave her because shed didnt love Aven, and by know we know  Harry definitely knows some things. Aven also mentions that her grandma said that her mom ran away when she was younger, and that could possibly be because of Malikai. We dont know how old Malikai is, but im assuming hes older since he has such a high ranking in the Mafia. Aven's mom is definitely my top suspicion. 

Aven: I dont strongly think Aven is Malikai's daughter, but i do think theyre related somewhere. I mostly think shes his granddaughter since Aven's mom being his daughter makes so much sense. We also know that someone in the mafia, im pretty sure Malikiai, sent skeleton mask to hunt Aven. We know that the Duplicity members are in on this, and we also know thats a reason they hired her. Why? I dont know. I think it could possibly be because Malikai is related to her and he could want to lure Aven's mom by killing Aven, if that makes sense. Or he wants revenge. 

Marissa: I dont know if shes Malikai's daughter, i dont really think it makes that much sense, but theres definitely a suspicion. I definitely think she is associated with the Mafia in some way though. When Niall is retelling the story about how Harry and Niall had slept with girls in the same room, Niall mentions how he thinks ones name was M-, then Harry cuts him off, even though he know who it is. That makes me suspect that Harry knew it was Marissa and didnt want Aven to know, and the "banquets" are usually Mafia meetings. Also (and i dont take credit for this part, i saw it in a tiktok i think) If you look closely to one of julez's first drawing of Harry and all of the names on his arm, someone zoomed in and saw "Mar" was visible, so that could be Marissa he slept with. Now, there is definitely a chance Marissa is Malikai's daughter, but if she was attending those meeting, she would have run. Plus, im pretty sure Aven has known her for years, meaning she probably hasn't been running everywhere. 

Make sure to comment or message me any theories or predictions, and let me know what you think of mine!!
