Jacob is Badass

THE figure of authority on the Island. He guards the Island from mysterious forces, he can see the future, he has the Touch, he weaves tapestries, and he can beat the crap out of Chuck Norris any day.

From "Ab Aeterno" :

[Jacob throws the knife to the ground.]

JACOB: Alright then.

RICHARD: What are you doing? What are you doing?

[Jacob picks up Richard and leads him to the ocean. He forces him into the water and holds him under. He brings up Richard.]

JACOB: Still think you're dead?!

[Jacob dunks Richard again.]

RICHARD: Stop!

[Jacob dunks Richard again.]

JACOB: Still think you're dead?! Why should I stop?

RICHARD: Because I want to live!

[Jacob drags him out of the ocean and releases him.]

JACOB: That's the first sensible thing you've said.
