I used to be the top soldier for the Stormcloaks, then i took a sword to the chest

Guard:
Let me guess, Someone stole your sweetroll!

Jarl Balgruuf the Greater:
Enough!I will not stand idly by while a dragon burns my hold and slaughters my people!

Paarthurnax:
Drem. Patience. There are formalities that must be observed, at the first meeting of two of the dov. By long tradition, the elder speaks first. Hear my Thu'um! Feel it in your bones. Match it, if you are Dovahkiin!

Malyn Varen:
And who are you to challenge me? I've conqured mortality itself. I've spat in the eyes of the Daedric Lords! This is my realm now, I've sacraficed too much to let you take it from me!

Dragonborn:
Fus Ro Dah!

Dremora:
I will eat your heart!

All:
You never should have come here.

Dirge (Thieves Guild Member):
I told they call me Dirge because I'm the last thing you hear before they put you in the ground.

Guard:
My cousin is out fighting dragons. And what do I get? Guard duty.

Babette, my girl - pack your things. We're moving!

Imperial soldier:
Been so long since I killed a Stormcloak, my sword arm's getting flabby.

[whispering] Dovahkiin.

Random child:
[when your character is only in underwear] Naked! Naked, naked, naked!

Perhaps we should find a random stranger to murder. Practice does make perfect.

Nazir:
You stink of death my friend. I salute you.

Hunters:
I've been hunting and fishing in these parts for years.

Mjoll the Lioness:
[after Dovakhiin drops an item from his/her inventory] Who left that here?

Dark elf merchant:
Back off! That's my armor now!

Mjoll the Lioness:
Not if I get it first!

Dark elf merchant:
Back off!

Mjoll the Lioness:
[drawing her weapon] That can be arranged.

[Mjoll the Lioness and Aerin fight the merchant til the merchant is killed]

Mjoll the Lioness:
[sheathing her weapon] That's the last of them.

I've got my eyes on you.

Cicero:
Let's kill someone!

Cosnach:
[when seeing a breath-taking view] Look at that. Am I drunk? I must be drunk.

Bard:
[singing] Oh, there once was a hero named Ragnar the Red, who came riding to Whiterun from ole Rorikstead. And the braggart did swagger and brandish his blade as he told of bold battles and gold he had made. But then he went quiet, did Ragnar the Red when he met the shield-maiden Matilda, who said; "Oh, you talk and you lie and you drink all our mead; now I think it's high time that you lie down and bleed!". And so then came clashing and slashing of steel, as the brave lass Matilda charged in, full of zeal. And the braggart named Ragnar was boastful no moooore when his ugly red head rolled around on the floor!

Alduin:
You do not even know our tongue, do you? Such arrogance, to dare take for yourself the name of Dovah!

Uthgerd the Unbroken:
[when spotting an enemy] Well, well. Another maggot to squash beneath my boot!

[when the Dragonborn is only in underwear]

Cosnach:
Either I'm drunk, or you're naked. Possibly both.

[when seeing a breathtaking view]

Njada Stonearm:
I've seen better. Well, maybe not.

Esbern:
In their tongue he is Dovahkiin - Dragonborn

My ancestors are smiling at me imperials can you say the same?

"I fight for the men I've held in my arms, dying on foreign soil. I fight for their wives and children, whose names I heard whispered in their last breaths. I fight for we few who did come home, only to find our country full of strangers wearing familiar faces. I fight for my people impoverished to pay the debts of an Empire too weak to rule them, yet brands them criminals for wanting to rule themselves! I fight so that all the fighting I've already done hasn't been for nothing. I fight... because I must."-Ulfric Stormcloak
