This took some time to draw, but I hope y'all like it! This scene is the final fight between King Stratus and his son. :D

Dust: Huh... wait... what the heck?! Where am I?!

Nublada: *she picks up the ring*
...I w-want to know if my brother is ok...*she tears up a bit*

Dust: ........

Nublada: I need to see him before we wake up...
...if he's ok...
*sigh*
It's a dream...but...could that have really been him...?
...It can't be. He was supposed to be dead-

Dust; I guess we’ll never know...

Nublada: Mhm...*sigh*
Who knows...
But now, we should wake up, my love.
There's no point in staying here...
*she hugs him and a cloud engulfs both of them*
*Dust fades back into the real world, and he wakes up safely beside Nublada*

Dust: ..........

Nublada: Hun...we're awake and safe now...
...I knew your sister would come to help us.
She saved your life...and my brother saved mine...
I'm still a bit curious about what happened with him.
...my father is now dead though. Forever, I'm pretty sure.
*she yawns*

Dust: Mhm...

Nublada: Which means that our children, once they're here, will be safe and we can raise them in peace. Plus Cirrus and Bloody don't have to worry anymore...

Dust: That’s right.

Nublada: *she smiles and holds up the diamond-shaped purple crystal*
So...I brought this with me...

Dust: ...oh.

Nublada: *grabs Dust's crown*
Ok, hun...so...this should fit here...
*she places the crystal into the missing slot*
....hm.

Dust: .....

Nublada: .....*it glows a bit and then fades out, as the crystal locks into place*
This gem was the one that I said my father stole way back when my sister came back to life.
It controls the Knightmares, and my brother must've made his sword out of the same material...capturing all those nightmares AND my father caused it to explode, killing them all and finishing off Stratus for good.
And now we have the crystal, and your crown is complete.
...I don't know if you'll gain control over the knightmares or not though.

Dust: Okay then...

Nublada: Yeah. *she places the crown aside*
That doesn't matter though. What matters is that we are alive and we finally killed my father, I hope.
Now we can rest without worrying about dying in our dreams...
...but there's no chance to meet my brother...I wish I was able to talk to him a bit before the fight. I didn't know he was still alive.
I never mentioned him before to you-

Dust: Yeah...

Nublada: I miss him a lot...
...the reason I thought he was dead was that after my mother was murdered and permanently slaughtered by Sir Soul, he went missing and my father later told us my brother had killed himself due to depression-
...turns out my father must've used that story as a cover-up. That was the day my father went completely insane anyway...so it seems that my father must've tried to punish my brother. Who knows why...but that's what I've collected.
I just didn't speak of him like I didn't speak much of my mother...just so I could try to not grow too sad over the loss of them.
*she looks down and sighs in sorrow*

Dust: ...

Nublada: Dust...you're pretty quiet...
...are you feeling well...?
Cause I'm feeling so many things at once right now...it's all a bit overwhelming, to be honest...

Dust: Yeah...

*the knives slightly knock back the knightmares, but they are left unaffected*

Stratus: Ah, you're a decent opponent I must admit...
...but you won't be for much longer...

*the knightmares charge at Dust, but Nublada knocks them out of the way*

*another Knightmare pops up from the ground and charges at Dust again with its sword*

Dust: *He doesn’t notice and attacks Stratus* THIS IS THE END!

Stratus: *holds his ground and grins*
Do your worst, emo boy!

*the Knightmare lunges from behind Dust*

Dust: *gets hit* .............
Did you just....
...wound me...?

Stratus: Maybe.

*the knightmares grab Dust by the arms, and another traps Nublada*

Stratus: And now it's the end for you...*the knightmares pull out their swords*

Nublada: Ah...father...please don't do it...

Dust: Wait... why do I hear...
Sis... wait... STOP!
IT HURTS!
IT HURTS IT HURTS IT HUR...
............

*the Knightmare holds its sword to Dust's neck*

Nublada: PLEASE! We don't want to die, father! Have mercy! *She begins to cry*

Stratus: There is no...mercy...*he smiles and approaches them*
...
???: STOP. RIGHT. THERE. I won't allow this to continue-

Stratus and Nublada: ?!

Dust: Heh...
Heheheheh....
HAHAHAHAHA!!!

???: Father...

Stratus: ...

Nublada: it...it can't be...?!

Stratus: Also, shut up Dust. Knightmares, kill him already. Your taking way too long.

*But when stratus looked, Dust was gone*

*Nublada appears by Dust's side in her dream form*
Nublada: .......My father must be manipulating your dreams, hun...
There he is...

*some of the purple clouds part away and reveal Stratus*

Stratus: Oh, if it isn't YOU TWO again...I was a bit...busy before you came...

Dust: *dashes infront of stratus* What the heck do you want now.

Stratus: Oh, I just want to see you and my daughter dead right now. I just want to CRUSH your damn skulls into the ground so you CAN PAY for what you did!!!

Nublada: Father, you already know I won't let it happen-

Stratus: *pushes Nublada aside* And yeah, I know you're having children. You're just ruining our family genetics by getting this boy's blood into our lineage...

Nublada: Oh. Shut. Up. My mother wasn't even from the Dream Kingdom, so you can keep quiet about that-

Stratus: Don't. YOU. Mention. HER.

Dust: Look, it doesn’t matter how many knightmares you send to kill me. You’ll fail. Just like last time.

Stratus: In my world, if you die here you'll die in the real world.
And no matter how many knives you throw at me...YOU'LL fail...I can't die now that I'm already dead...
...And even if I can't kill you, I can always kill my daughter...*a Knightmare picks up Nublada*

Nublada: AH- Put me down!

Dust: Wait...
...
Why do I feel...
...
I hear her voice.
The voice of my SISTER...

Stratus: ...hah. That's hilarious.

Nublada: Father, you wouldn't kill ANOTHER of your children, would you!?!

Stratus: I didn't kill him. He killed himself, and we miss him, you know.

Nublada: ...*sigh* I know...I just...
Dust, we're gonna need your sister's help...I hope she can give you strength...

Dust: I’ll do what I can alone... she’ll know when I need her... COME AT ME STRATUS!

Stratus: *smiles* As you wish...
*he summons two more knightmares and he pulls out his sword*
You're never going to make it out of here alive!
*he lunges at Dust*

Nublada: *punches the Knightmare holding her and escapes its grasp*

Dust: *throws knives at both knightmares and dodges Stratus’ attack* You thought I would let you hit me? HILARIOUS.

???: Oop, guess it's not my time to come in-

Me: Yeah, go back.
Ahem-

Stratus: Where'd that scoundrel go!?!? How did Dust escape...!?

Nublada: ....Hun?

Dust...?: Kid. *looks at ???* Don’t screw this up, our bloodline depends on it.

Stratus II: Of course. You don't know me, but I think I know you.
So bring us to the King and my sister...
...they could use a visit from me about now...

Dust...?: Trust me, you might know my BROTHER... but you have no idea who I am/

Stratus II: *smiles a bit*
Ah, I see.
Well, you know my sister...
And we must help both of our siblings.
For our bloodlines.
*he pulls out his crystal ring*
Let's do this.

Dust: *he seems to be in control again* Agreed.

*he emerges from a cloud where Stratus is*

Stratus II: Father...

Stratus: Son...

Nublada: ...n-no...it can't be....?!?!

Dust: *grabs Nublada and r u n s*

Nublada: Brother!?!? How!?!?

Stratus II: Hey sis...don't worry about me. Go with your husband and get as far away as possible.*he smiles*
I'm glad to see you once more...

Stratus: *pulls out his sword and surrounds Stratus II with Knightmares*

Dust: Come on! Don’t ask how I got away from the knightmares!

Stratus: But how the HELL did you get away from those knightmares, Dust!!?!?

Stratus II: Help from a loved one...
And that's how you'll end, father...

Dust: Because... I have my family with me. I have something that you never respected. So, it’s time to end this...

Stratus II: Exactly what he said! Think of what you did to me after my mother was killed!
Look what you've done to my sisters' lives!!
And as he said...
...this is farewell, father...
*he absorbs the knightmares into a sword made of the purple crystal*

Stratus: No! This can't be! You disgrace of a son-

Stratus II: Dust! Take my sister and yourself away...
I don't want y'all to get hurt!
*he starts running at Stratus*

Dust: ...nice kid. *carries Nublada and runs*

Stratus II: This is your last moment, father!
*he thrusts the sword into Stratus' chest, now face-to-face with him*
I hope that I lived up to your name...
*he smiles*

Stratus: Y-you...s-son....

Stratus II: Say hi to mother for me...
*The king is absorbed by the blade, and Nublada and Dust see a massive explosion from the area*

Nublada: I-

Dust: *hugs Nublada and cries* I saw them... my family...

Nublada: *hugs Dust and cries with him*
I know...I felt them too...
And I...saw...
...
M-my brother.......
...how did-

Dust: I don’t know... but... I think we did it.

Nublada: Mhm...
*a crystal ring lands on the ground beside them, alongside a diamond-shaped crystal*
Seems that the explosion launched these here...
But I think that now...knowing how much of a genius my brother is...my father has been entirely destroyed.
Thank God.*she hugs him again*

Dust: Well... what do we do now?
