We have failed the Gods. We have behaved like humans. They gave us every opportunity to be better people and we have all failed. There's only one way to stop our settlement from descending into chaos. We must offer a sacrifice which will mean something. A sacrifice that will give us a second chance.

Floki

Lagertha: Astrid, stop, I don't want to kill you.
Astrid: You have to kill me.
Lagertha: Why?
Astrid: Otherwise we will kill you.
Lagertha: You helped me. You didn't betray me. I know you love me.
Astrid: There is no use, Lagertha. I have to die. I cannot have this child.

Bjorn: I heard you singing with your brother. This must be hard for you.
Halfdan: Let me tell you something. I owe my brother so much, but I owe you far more. You took me on a great adventure. You showed me that life has more to offer than fighting for land, or for worthless glory, against your own Viking brothers. And if I have to die today, so be it. I'm ready for Valhalla.

Bjorn: Maybe we can negotiate some sort of agreement. Perhaps King Harald and Rollo will see sense.
Lagertha: I wouldn't count on it. They are in a position of strength now.

Ivar: If you still thought you could win you would not be here, Bjorn. The fact is you're afraid.
Bjorn: I am not afraid. This changes nothing.

Lagertha: You don't have to fight for us.
Heahmund: Of course I do. It's why you saved my life. You hoped that I would take up my sword and fight for you against Ivar.
Lagertha: Will you?
Heahmund: I will fight for you, Lagertha. I will die for you.

We just lost the battle. So many died. Do you really think I should be happy?

Astrid

Bjorn: Are you ready my friend?
Halfdan: Of course.
Bjorn: You have to fight against your brother.
Halfdan: It is the same for you. Some trees have to fall in the forest.

Astrid: I think we should go.
Ivar: And I think we should wait. Good things happen to people who wait.

In the name of my father, attack!

Bjorn

Ivar: Are you ready to deal with Ubbe? Will you kill him if you have to, even if he is your own flesh and blood?
Hvitserk: If I kill Ubbe, won't my fate be assured?

Heahmund: Do they frighten you, your brothers?
Ivar: No, maybe Bjorn, just a little. I don't find him very smart, but he is a great warrior. They call him Bjorn Ironside.

Vikings Season 5 Quotes

Ivar: Stay. We need you just as much as my father needed you, but instead you choose to run away, you coward.
Floki: Stand up and say that to my face.

Floki: I have to leave Ivar. With Helga gone, there's nothing left for me here. This world no longer interests me. That's why I must submit myself to the tides, and the winds, and the will of the gods. Come what may.
Ivar: My heart is broken.
Floki: It will repair.
