The picture of brock and his mom made perfect sense. They were outside their house waiting to kill Jessie, either walt gave them a pic of who to look for... or they took a pic while they were there. For someone like Jessie who doesn't much care about his own well-being but cares immensely about the lives of 'innocents' it's the perfect way to convince him to cook.
Hiding under the car also makes perfect sense. Walt is in Jessie's head... he tells Hank he thinks Walt is the devil, smarter and luckier than you etc... then when he FINALLY thinks they have Walt beat... the nazis show up and Walt is about to win again. Jessie isn't just hiding under his car, he is cowering in fear of Walt and people in fear don't make the best tactical decisions... they tend to do whatever is fastest (like getting under the car).
Nazis who run a nationwide prison syndicate capable of killing 10 inmates in different prisons within a 2 minute window are not a group of 5 or 6 guys capable of taking 70million and walking away. They likely have 100s or 1000s of mouths to feed including family of the incarcerated and a network of 'brothers' nationwide. VERY few people would ever walk away from 150+ million per year just because they found 70M once.
Giving Walt a barrel and letting him go was a very stupid move. Exactly the same kind of stupid move walt made by letting Jessie live so long. Exactly the same stupid move the Mexican Don made by letting Gus live. Exactly the same stupid move so many people in power make when they think they have succeeded. It's the GWB "mission accomplished" mindset that power and temporary success breed when they are allowed to become hubris and arrogance... and it usually bites the person in the ass. That is the entire point of Shelly's poem Ozymanidas. The king of kings always fails... and in this episode the nazis had their Ozymandias moment by letting Walt leave with a barrel of cash...
The pace of this episode was incredibly fast. They closed up so many loose ends and plot points... would jessie find out about jane's death, how would walt jr find out whats going on, what would happen to hank, etc etc.... each of those things could easily have been its own episode. By closing up so many plot points they reached their goal... leaving us with two more episodes and ZERO ability to predict what happens next. Nobody has more than a complete guess as to what might happen next. We are all in the dark now.
