Yep, that is the famous Southern drawl... two variations of it. You have the common citizen version and you have the higher-class version spoken by Captain Lee, since I have grafted him into a family that LITERALLY has been high-class in the English-speaking world since the time of Richard the Lionhearted (so, around 1,000 years!).

Here's the other thing about the Southern drawl ... it is SLOW, so read it again, and imagine the citizen coming up saying what he said slowly, giving time for Captain Lee's fury to go absolutely through the roof, and THEN imagine Captain Lee picking out each and uttering every devastating word even more slowly, just melting the bigot down over a slow, high heat...
