Did the minerals thing have any relevance to the main story line besides Hank being able to use that as an excuse to get out of the house with Walt?Something is going to drives Hank's wife insane and she's going to shoot him. You can watch her as she gets all pissed off at his "rock" collection. (THEY'RE MINERALS, MARIE!) I just can't imagine her not snapping even with Hank back at work. Hell, she was stealing shit again. My bet is on Marie...whether it's outting Walt (finding out from his wife) some how or killing Hank.
It showed what he was doing while he was stuck in bed due to injuries.Did the minerals thing have any relevance to the main story line besides Hank being able to use that as an excuse to get out of the house with Walt?
