He goes. He is very quick about it, but he takes the time to make sure he is properly dressed, because appearances are important - his formal surcoat, with the sign of the snowflake argent-on-sable front and back; but no armour and no helmet, to make the point that he doesn't need either. And his sword, to claim knightly status; but no other visible weapons, because he doesn't mean to hurt anyone while he's there.

When he arrives at the Stone Table, he is very careful on his approach. It wouldn't do to miss a sentry and be attacked before he can explain himself.
