I was actually hoping it would be a dud. Kind of a metaphor for Walt this season.

Yeah, I've learned more this season about how to run a car wash than I have about cooking meth.

I noticed Jesse's video game gun was the same shade of green as the box cutter.

The less Skyler White there is in an episode, the better it is. Especially when it's early on, and I get that chore out of the way.

More importantly, how did he get that "hallucinate Gale Boeddicker" DLC?

Yes, I think it might come back later, but honestly, what can you learn from minerals just by looking at them? It's not like he ordered any geology/chemistry books. The only thing it would be good for is identifying raw minerals, like "Hey, that's a chunk of quartz."

Wouldn't it be great if Hank has known it's Walter all along, but he's just shielding this knowledge? Certainly the Corvette story would have raised another flag.

I think the walls are gonna close in on Walt and he's gonna take the "Disappear" offer and you're gonna end the season, wondering how the hell the show expects to go another 20 episodes with this guy in a sort of witness protection program.
