Why does Ragnar want to see the king?

Does he want an apology from Ecbert for murdering his people (he did, right?), does he want to perhaps usurp him (fat chance but would be hilarious), does he want an alliance to raid Paris and kill that worthless brother of his (I wish)?

What's the dealio?

And why does Floki look like Ragnar now, and why are they using so much black eyeliner!
