Irreconcilable Paths/Script

Opening

(In a rainy field)

Chrom: ...Risen. And lots of them.
Lucina: Be careful. I feel a dark power emanating from them. Darker than usual. They resemble the monsters that drove us to the brink of extinction in my future…
Chrom: I feel it, too. They seem stronger than any we've faced before.
Lucina: Perhaps we needn't fight this battle. We're miles from the nearest village... These Risen may never threaten anyone.
Chrom: They aren't the only power at work here. There's something else... Something strong.

In battle

Walhart: Useless husks! Do you bend the knee to me already? Pah! I've no use for blind obedience. I need you to face me! I was driven off the path to conquest, and only blood will see me returned to it. Only HIS blood!

Battle quotes

Walhart enters combat

Walhart: In this land, I have crushed a multitude of Risen and made them my own. You snuffed my dreams of conquest... I dare you now to snuff the spark of life within my breast!

Walhart enters combat with Chrom

Chrom: Walhart! You survived?!
Walhart: My heart beats no more... But the flame of life within me refuses to gutter out. This marks the third and final time our blades will cross!
Chrom: The war has ended, Walhart! We've no reason left to fight.
Walhart: We have EVERY reason! A conqueror rules by strength alone. Defeat is death, and I must rise again!
Chrom: That's utter nonsense! The fell dragon is reborn and plans to destroy this world! If you're really so dead set on battle, then fight at my side!
Walhart: Such arrogance. This world is mine! I'll suffer no one to harm what is mine, be they man, dragon, or otherwise.
Chrom: Then let's strike him down together.
Walhart: Words will not divert my course. Only steel! If you would claim me, draw your blade and make it so!
Chrom: *Sigh* Fine! We can fight again... But when I defeat you THIS time, you WILL join my cause!

Walhart is defeated

Walhart: Ngh... Then the exalt-to-be is...the conqueror in true...

Ending

If Chrom fought Walhart

Walhart: ......
Chrom: You gave your word, Walhart. Now fight with us.
Walhart: First I must know how you defeated me. I have never lacked for strength.
Chrom: No, you're far stronger than me. Even now I think that's true. ...But you stand alone. My own strength is but a fraction of the strength I wield. My allies hone and temper me. They boost my morale and guide my actions.
Walhart: You tread the path of kings.
Chrom: What?
Walhart: You rule by winning hearts. ...I rule by winning battles. We are opposites, you and I. I cannot change. I tread the path of the conqueror, and conquerors walk alone. However, I am curious to see just how far your kingly path can lead you...

Regardless of if Chrom fought Walhart

Frederick: The wounded have been treated and the horses loaded. We should hurry on, milord.
Chrom: The path of the conqueror…
Frederick: Milord?
Chrom: Sorry. Just thinking out loud. You know, honestly I'm a bit jealous of Walhart. He stands for strength above all things. He has no regrets, no doubts. He's a juggernaut that charges forward and mows down whatever gets in his way. I'm...not like that. My steps are often plagued with question and worry.
Frederick: Perhaps such emotions are part and parcel of your path, milord. Not obstacles to it.
Chrom: How do you mean?
Frederick: The doubtless man's path is straight, but not always true. A juggernaut does not pause to correct trajectory. It merely presses on. But by stopping, doubting, and occasionally doubling back, you keep a truer course. I could not serve a conqueror, milord. And I pray you not think prudence a flaw.
Chrom: ...Thank you, Frederick.
Frederick: Not at all, milord. Shall we, then?
Chrom: Of course. Forward! ...For now.
