Avengers: Infinity War2018

Rocket:
You speak Groot?!

Thor:
Yes, they taught it on Asgard. It was an elective.

Groot:
I am Groot?

Thor:
You'll know when we're close. Nidavellir's forge harnesses the blazing power of a Neutron Star. It's the birthplace of my hammer; It's truly awesome.

Rocket:
[to himself] Okay, time to be the Captain. [to Thor] So, dead brother, huh? Yeah, that can be annoying.

Thor:
Well, he's been dead before. But this time... I think it really might be true.

Rocket:
And you said that your sister and your dad...

Thor:
Both dead.

Rocket:
But still got a mom, though?

Thor:
Killed by a Dark Elf.

Rocket:
A best friend?

Thor:
Stabbed through the heart.

Rocket:
You sure you're up for this particular murder mission?

Thor:
Absolutely. The rage, vengeance, anger, loss, regret, they're all tremendous motivators. They truly clear the mind... so, I'm good to go.

Rocket:
Yeah, but this is Thanos we're talking about, he's the toughest there is.

Thor:
Well, he's never fought me.

Rocket:
... Yeah, he has!

Thor:
Well, he's never fought me twice. And I'll have a new hammer, don't forget.

Rocket:
Well, it'd better be some hammer.

Thor:
You know, I'm one thousand and five hundred years old. I've killed twice as many enemies as that, and every one of them would have rather killed me, but none succeeded. I'm only alive because Fate wants me alive. Thanos is just the latest in a long line of bastards, and he'll be the latest to feel my vengeance. Fate wills it so.

Rocket:
And what if you're wrong?

Thor:
[mirthless chuckle] Well, if I'm wrong, then... what more could I lose?
