You are not like anybody else. Be yourself, Floki. This world, it is too small for you.

Helga

Floki: What are they doing? Where are they going?
Ivar: To Repton, I imagine.
Floki: To the boats? They are going for our boats? Oh, you crippled bastard! You were right! You were right! Oh, you bloody, mad genius. You were right!

Ivar: Listen, come with me, Bjorn. Let's investigate the battlefield. Perhaps, instead of a narrow and small place, we should stretch the battlefield across a large area, many miles. And use the landscape. Ditches, hills, woods. What do you say?
Bjorn: If it works, it is a good plan. If it doesn't, then it is a bad plan.

Egil's wife: Just tell them Egil!
Egil: If I do it it is for you, not for me. I am dead anyway. Perhaps they will spare you. I was paid by King Harald Finehair.

So this is what the grunting of the little pigs was all about?

Floki

We are all equally Ragnar's sons, but we are not equal in battle. So I will take the lead. I will establish the battle plans, and I will give the orders. Do you understand that?

Bjorn

I've been told your god is a carpenter. And guess what? So am I.

Floki

Aethelwulf: You're not behaving like a king anymore. People are already talking about it. You're distracted, you're withdrawn, you seem unsure, hesitant. Once you were firm, you were strong.
Ecbert: No, I am filled with doubts, and I have begun to believe that being firm and strong was the illusion, and that I am unsure now because it is the most honest way to be.
Aethewulf: Not in the face of a great heathen army that have come to destroy us.

Helga: What happened to you?
Floki: I wish I could say.
Helga: Why don't you try?
Floki: I don't want to be imprecise.
Helga: It's not a riddle.
Floki: No, it's a truth. I just don't know what the truth is.

Floki: Us? You are no longer a part of us, Rollo.
Rollo: But what is us, Floki, is changing, only you won't accept it.

Ivar: What is it?
Floki: It's your legs, Ivar. It's your wings.

Lagertha: You had no right to free my slave without my permission.
Ubbe: I don't remember you asking permission to kill my mother.
Lagertha; That's different. I'm queen now.
Ubbe: I know, I just don't know for how long.

Vikings Quotes

I wanted to step out of your shadow.
You understand that, don't you?

Rollo

Who needs a reason for betrayal?
One must always think the worst Ragnar, even of your own kin.
That way, you avoid too much disappointment in life.
