"Father, I let you down! Forgive me!" Should I know something? Was this guy important? Or his father? Whatever.
No, they weren't.
Also regarding that, later another Knight of the Round will be introduced. Her sole purpose is to DIE FIVE SECONDS LATER in place of the ONLY Knight of the Round with ABSOLUTELY NO SPEAKING ROLE. You might possibly confuse her with the other Knight of the Round who also dies five seconds after her first line of the episode, but she appeared in a previous episode (and talked!). HER sole purpose is to be completely ineffectual and forgettable. They are both completely unimportant.
"Send a postcard." Hahahahaha! Best one liner.
In the original, she just said "sayonara" (with that same really disgusted look on her face). In fact, in the dub Kallen just seems to have a couple of randomly thrown in one-liners, now that I think about it.
