Hi, non-American here. English is also not my first language. I noticed many characters in BrBa will say a phrase about their opinion, then end with with "is all". Like how in the pilot Jesse said sth like "Some straight like you... suddenly decides to break bad? It's weird, is all." I heard Jane, Walt, Skylar and some others say it like this too. Then I noticed I never really hear ppl talk like this in other American shows that are not set in New Mexico/ABQ. Just out of curiosity, is this the local slang? Is there any other fun quirks about the show that is native to the location that ppl usually don't know about?
