King Varian Wrynn

After defeating Garrosh Hellscream, for Alliance he says:

At last, the time for justice is at hand. This monster will answer for each and every Alliance life that we have lost in this war.

(Option 1) Garrosh will pay for his crimes.

After Garrosh Hellscream's defeat cinematic, for Alliance he says:

Thank you, hero. You and your companions were the tip of the Alliance spear: Your work exploring Pandaria, securing the Vale, and ultimately assaulting Garrosh's stronghold is what made this victory possible.

Our triumph here will put a stop to the fighting in Kalimdor, but even in peace, there's much to be done - here, back home, and elsewhere.

(Option 1) What's next for the Alliance?

We are unified like never before. We've bought our people security in Kalimdor, an end to the blockade, and an end to the total war that's split so much blood on either side of the great sea.

Now, to the work of winning the peace. I would like to station a garrison near Theramore. We need to investigate the cleansing the plague from Gilneas lands so they can rebuild. We must contain Sylvanas.

From here on forward, the Alliance will be proactive. Never again can there be another the likes of Hellscream.

(Option 2) Why not keep fighting?

I understand your desire to inflict more suffering on the Horde. But when do we stop? How many more Alliance will number among the dead if we invaded Thunder Bluff, Azshara, and the Echo Isles? And how would we govern the conquered people?

The Pandarens always question why we fight. Today, we've won justice, and have given the Horde an opportunity to atone by supporting their rebellion. Further bloodshed would be for vengeance alone - and it would reap vengeance in return.

After Garrosh Hellscream's defeat cinematic, for Horde he says:

I have nothing to say to you, <race>. Your people have a lot to answer for. But maybe this is a new beginning.
