It's funny how, even though they speak completely broken english and is most gibberish, you can understand them fully. If you really listen to them, they make alot of damn sense. It's like talking to a brutally honest toddler, they make their message clear without fancy words or proper grammar. They just tell you like it is.
The funny thing is, these guys aren't completely stupid. They can follow whe Geralt talks in a normal pace, which means they also know when someone talks to them with the expectation that they are dumb.
