Here are my favorite parts from episode 89
Yu-Gi-Oh! Zexal Episode 89: Darkness Dawns
Astral: "The Numbers that are being used by the Barians are far more powerful than any monsters Yuma and I have faced before, especially when they evolve into Chaos Numbers. We will not continue winning out duels unless I find a way to become stronger, but how? *gasp* What is happening? The Numbers... it seems as if, they are trying to communicate with me."
Dark Mist: "Astral."
Astral: "Huh? You! Number 96!"
Dark Mist: "You are not powerful enough to defeat the Barians."
Astral: "I thought I'd finally seen the last of you."
Dark Mist: "Well luckily for you, you were wrong, you need my Astral as to when you know it. Release me from the confines of the key and in return I will lend you my help."
Astral: "You know I will not except your offer."
Dark Mist: "Do not dismiss me so quickly. I know that you are stumbling around hopelessly in the dark. You do not have the strength to continue on alone. You need me. Face the facts Astral. You may be light, but I am darkness. Light can only shine in the dark. Without me you will never be complete."
Duel against the Duel Giant
(Interactions between Yuma, Astral & Dark Mist)
Yuma: "He counters every single move we make."
Astral: "We are strong enough."
Dark Mist: "You will not win until you accept the one thing you lack, you need... my help."
Yuma: "What does this guy want Astral?" He's nothing but trouble!"
Dark Mist: "You have me all wrong. I am here to help. This opponent is testing Astral in order to see if he is worthy of keeping the Numbers."
Astral: "Worthy?"
Yuma: "That doesn't make any sense. Why would that guy care if Astral has the Numbers?"
Dark Mist: "Astral, you know I am right. You also know that you need my power to defeat him."
Yuma: "What dose he mean we need his power Astral?"
Dark Mist: "It is true, I have things that Astral lacks. Anger, envy, malice. You need them all to win."
Yuma: "We don't need any of that stuff and we never will!"
Dark Mist: "Or so you think. Take my advice and think it over carefully for you turn me down Astral. Just remember... this is not the Human World, I wonder what will happen to your friend Yuma if you lose?"
Yuma: "Astral, he's wrong! We can win this without anyone's help!
(Astral release Dark Mist)
Astral (thinking): 'This next turn will be our last. Unless we summon an Xyz Monster, the field spell's effect will raise our life points. But if we do bring out an Xyz Monster onto our field, strength his monster will gains will be devastating, both for myself and for Yuma.'
Dark Mist: "This is not the Human World, I wonder what will happen to your friend Yuma if you lose?"
Astral: "Yuma. All right, Number 96! I will free you!"
Yuma: "No Astral, you can't! Please don't do this!"
Astral: "Number 96, make sure you fulfill your end of our bargain!"
Yuma: Why Astral? Why are you teaming up with him?"
Dark Mist: "I promised that I would help you win this duel and I will. You must summon Dark Mist... quickly!"
Yuma: "No, I won't!"
Astral: "You must! It is the only way we can win!"
Dark Mist: "Now summon Dark Mist and I will seal our victory!"
Astral: "Do it!"
Dark Mist: "Now."
Yuma: "All right!"
Dark Mist to Astral: "Convinced yet? Surely you must see now that you do need my power... the power of darkness."
(The Numeron Code)
Yuma: "Hold up, where are we now?"
Astral: "The Door has put us onto the path of enlightenment Yuma. I finally understand what the Numbers have been trying to tell me. Of course, yes it all makes sense. Yuma I remember now! There is a card that contains the meaning of the entire universe. Within it can be found any answer you could possibly seek! Everything from the origins of time itself, to the ultimate destiny of all reality."
Yuma: "Wait, all that stuff's... in a card?"
Astral: "It is a very special card Yuma. The card is so powerful, that is can determine the fate of every world. This may be hard for you to understand and even harder for you to believe. It is the card the created our whole universe... The Numeron Code."
Yuma: "Where is it?"
Astral: "As we collect the remaining Numbers, we will learn the card's location. The Barians are desperately seeking this card, but I must obtain it first!
(Number 96's warning Astral)
Dark Mist: "Astral you kept your word and set me free. Thank you. And I promise you, there will come a day when you will need my dark powers once more. We will meet again."
(Astral thinking about what Dark Mist said)
Astral (thinking): 'Number 96 seemed certain that I would ask for his help again. Will you truly need his powers to carry out my mission? Am I destined to draw upon his darkness this in the future?'
