Large Ham: Lord Flashheart really likes his own voice.
Shut Up, Hannibal!: On being caught by Baron von Richthoven, Captain Flashheart appears to listen to the Baron's gloating speech for about a minute before suddenly shooting him dead mid-sentence with the observation "What a poof!"
Possibly to the point of being a subversion, since the Baron's speech is more along the lines of "Wow, I finally get to meet the great Lord Flashheart! As men of honour, we'll surely have so much in common and will have a glorious and dignified duel with each other!" than a Break Them by Talking, not having realised that Flashheart is in it for England, not for personal glory or the love of combat.
Edmund: Unfortunately, most of the infantry thinks you're a prat. Ask them who they'd prefer to meet. Squadron commander Flashheart or the man that cleans out the public toilets in Aberdeen, they'd go for Wee Jock Poo Pong McPlop everytime.
Unishment: Richthofen intends to punish Blackadder by sending him back to Germany, where he will spend the rest of the war teaching German schoolgirls home economics. He clearly doesn't know who he's dealing with.
Richthofen: For you, as a man of honour, ze humiliation vill beUNBEARABLE!
