Well we know from the season beginning that Walter is alone on his next birthday (he has to arrange his bacon himself) and he bought a bunch of guns, and then got the ricin in a house that was ransacked and had ‘hisenburg’ painted on the wall.

Everything has to lead up to that

So Skyler and the kids are gone.

The house is fenced off, but Walt is not in jail... and planning something bad

The bedroom door kicked in (means what?)

I dont remember what the signs on the house say (not police or FBI signs, were they? more like HazMat?)

Do we know that those events occurred in that order? Could his trip to his ransacked house have come before his birthday in the diner?

Also remember that the next door neighbor is giving Walt the stink-eye in that first episode (509?). In the next episode they show her talking to Walt and she’s very nice to him, so somehow between then and “now” when Walt comes back to get the ricin, the negative information about Walt has made its way into the community, at least enough for the next door neighbor to know about it.

I thought the signs were foreclosure, and you have to factor in the way his neighbor lady dropped her grocery bags when she saw Walt. The reaction of the neighbor lady in the first scene of this season was neighborly.
