Awakening DLC - Joker/Frederick conversation

JOKER:  What the hell is your problem, you son of a bitch?
FREDERICK:  ... What is it? It's rude to walk up to others and suddenly call them sons of bitches.
JOKER: Excuse me!? Look who's talking here!
JOKER: You were looking at Master Kamui with a suspicious gaze, were you not!?
FREDERICK:  I was making sure that they would not cause harm to Master Chrom and his companions.
FREDERICK:  Isn't it natural to doubt someone whose origins are unknown to you?
FREDERICK:  Once the harm is done, it'll be too late.
JOKER: ... Tch. I don't like your attitude, but I can't disagree with what you've said.
JOKER: I was suspicious of your master as well, after all. [transcription error?]
FREDERICK:  What was that!? You shameless-!
JOKER: Well? What is it? You wanna go?
FREDERICK:  ... Of course not. I wouldn't stoop to your level.
FREDERICK:  I must not lose myself to emotions simply for the sake of loyalty. My devotion to my master surpasses that of anyone else.
JOKER: What was that? I won't just let that statement slide. I'm far more devoted to my master than you are.
JOKER: For one thing, I brew a new pot of black tea every day for Master Kamui, each with its own unique aroma.[transcription error?]
FREDERICK:  Hahaha... You still have much to learn. Every day, I go on ahead  ofMaster Chrom and Master Liz and remove every last weed and pebble in their path.
JOKER: Kh...! But for my master's sake, I wake up early every morning to inspect the equipment, polishing each one until they shine brighter than they did when first bought!
FREDERICK:  If my master wishes to eat fish, I would cross three mountains to obtain it for him, and if he is about to let out even the slightest sneeze, I offer him my own handmade scarves!
JOKER: ...
FREDERICK:  ...
JOKER: I see. You're no slouch at all.
FREDERICK: Yes... and neither are you.
JOKER: I do not accept your master, but you have earned my recognition.
FREDERICK:  How kind of you. And you may have my recognition as well.
FREDERICK:  You are the first person I've met who's as diligent as myself.
FREDERICK:  I'd like to talk to you a little more, if we weren't on the battlefield.
