Director of photography Michael Slovis (who joined in Season 2) wasn’t fully on board yet, but Season 1 still uses brilliant visual metaphors. The desert is a character—a lawless expanse where morality evaporates. Walt’s transformation is mirrored in his clothing: from green (family, life) to black and brown (death, crime).
We learn about Walt’s past: he co-founded a company called Gray Matter but sold his shares for $5,000. That company is now worth billions. This backstory explains Walt’s deep resentment and his drive to "provide" for his family. The episode ends with Walt accepting chemotherapy but lying to Skyler about the money coming from his old partners, deepening his web of lies. Breaking Bad 1 Temporada
