Season 5 Episode 1 Opening Scene
Okay there are a lot of misconceptions about this scene so I thought I would clear some up for some people so they are not so confused when the new season airs. Also I have a great suggestion which many may not have thought of!
1. Walt is not in New Hampshire. He is there using a fake ID and driver's license. When the waitress realizes he's from NH she says " Your a long way from home" and Walt replies with how many hours (roughly the distance between NH and NM)
2. Everyone knows Walt buys the big machine gun but just to be clear he does not need that kind of gun to kill Skyler, Saul or Jesse.
Now one thing I thought of. Walt makes the "52" out of his bacon which Skyler does for him every year on his birthday (this means he is on the run or she is dead maybe but that's unclear for now) but the waitress tells him his meal is free with a valid ID.
So, either his fake NH ID has the same birth date on it, the waitress just didn't notice the fake ID's birth date was different from the current date, Walt was celebrating his fake ID's birthday to get a free meal (which he didn't want), Walt showed her his real ID and now that waitress can ID him, or Breaking Bad has made a serious continuation error which I highly doubt.
My thinking is that Walt showed her his true ID and left her the $100 tip in order to distract her from remembering the fact that he lied about where he was from to her. But is the DEA comes sniffing she is definitly going to remember the man who gave her such a large tip.
Anyways, I haven't rewatched the episode so I might have missed something on that part so suggestions are welcome.
