A pic leaked a while back:
That looks like VAMONOS PEST on the back of Jesse's shirt. Could he be an exterminator? What does that have to do with meth?
Well, exterminators sometimes do what is called a "tent fumigation", aka they seal a house in a big rubber tarp so none of the pesticide leaks into the neighborhood....
Fumigation - Wikipedia, the free encyclopedia
In the latest promo, you can see what looks like a mini-lab surrounded by plastic....
Are you guys seeing what I do? A fake bug extermination company that sets up a lab inside a house, cooks a batch of meth, and moves to the next house. Tent fumigation usually takes 24 hours, so they have plenty of time to cook. I assume the fumes would kill any bugs present, too.
Could be wrong, but a cool idea.
