5x15: Granite State

Observations: “Jesse reaching for the grate (symbolically, reaching for the starlit sky) resembles the scene where he climbs the ladder to kill the mighty fly once and for all in 3x10, both visually and even to an extent thematically if you consider the notion of choices and their consequences which was heavily present in the aforementioned episode and subliminally implied in this one.”
Aria Mohtadi’s Breaking Bad Observations

5x14: Ozymandias

You both worked on the episode “Fly” as well (Johnson directing, Walley-Beckett co-writing), in which Walt almost told Jesse the truth about Jane. Now, you got to realize the moment.
A - Walley-Beckett: “I was really excited to get to have part A and part B. We had the dance up to it, and that horrible, horrible moment of anticipating that Walt was gonna spill it in ‘Fly,’ and this time it comes out of the blue. And it’s just cruel.”
Q: At first you think Walt is almost going to offer an apology. It did look like he was sorry for a split second!
A - Walley-Beckett: “Right? But no. That is pure Heisenberg and, truly, his murder of Jesse. He just kills his spirit.”

3x10: Fly

Observations: “’A fly in the ointment’ is a saying which captures a running motif in Walt’s life. When he is overwhelmed by his situation he focuses on a small imperfection that he can obsess on instead. When he received his cancer diagnosis (1x01) he responded to the doctor’s dire warning by pointing out a mustard stain on his shirt. Recently we have seen him spend time cutting sandwiches (3x06), skimming pools (3x02) or fixing tables (3x07). Now apparently he wishes he was dead and not having to fret over being under threat from Gus so he fixates on the fly.
