RICHARD MADDEN: At the start of the scene, bread and salt is passed between us all.
And in this world and in the kingdoms, it is a symbol
of the leader of the house taking you under their protection.
This was something that derives from actual medieval customs
that I've used for the books.
Eating the salt and bread signifies that you are taking guest right.
That you are entering into this ancient and sacred covenant
where the host agrees that the guest will be safe in his home
for the extent of their stay.
Catelyn has been very nervous about this return to the Twins
because she knows just how vile Walder Frey can be.
And that he's a man that should not be crossed
and who holds serious grudges.
But once they eat the bread and salt,
she feels a degree of confidence
because she can't conceive that someone would break this covenant.
This is sacred and this is something that you don't mess with.
