one of the things that's so brilliant about the writing BrBa are how parallels can be drawn between different characters actions and how past actions are subtly referenced later:
Jesse "the rabid dog" changed up in the lab
Walt is able to roll a barrel
Hank and Gomez buried in the same spot where the barrels were (Walt dug their grave)
Walt basically did to Jesse what he said Hank did to him in his "confession" video
The stuff with Walt Jr and Holly was pretty heartbreaking. Great episode.
Special shout out to Meth Damon the Sociopathic Android with his "sorry for your loss", followed quickly by "Let's torture Jesse"
