My mother insists there exists a cut scene/episode from Breaking Bad season 2 that she saw on my uncle's old German season 1/2 DVD in ~2012.

According to her, this episode features Walter having trouble with rival gang members (not the ones from Season 3 he runs over). To get rid of them, he becomes a construction worker, and over the course of a few weeks, he takes the equipment from the construction site while off the clock and digs a hole in a street. He then covers the hole with a tarp to disguise it. Once the hole is done, he lures the gang members into driving across the tarp and thus falling in the hole. He then buries them alive in concrete.

My mother completely stands by the fact that this episode exists somewhere. I haven't been able to find a trace of this episode existing anywhere. She says she really wants to watch it again because she considers it one of Walt's best plots in the whole show.

So, does this episode really exist or is my mother just crazy?
