Now the flashback:
Müller, the reluctant agent.
& his frustrated partner, Phantom; though he has hopes of persuading Müller to finish the mission, he uses tough-guy approach.
Inside Müller's chest is a small device, I cannot identify it, though it is obviously needed to destroy the reactor.
between this & the next image, the kids go and play, then take a ride and enjoy the view.
Yet, they see this, the local nuclear reactor, which is Mueller's target.
He is thoroughly upset about this reminder of his mission, one that he dreads.
Though Atom & family try to assure Müller that he has no obligation to complete his mission, he knows he is helpless to avoid it.
When Müller says his target was genshiro (nuclear reactor), the family freaks out. Atom dutifully reports to Ochanomizu, then Müller is marked for death when Tawashi finds out.
You may recognize these cops, their first appearance was as Rommel's henchmen in #29,
Memorable Day.
The skinny guy also had previous appearances, though I need to find his J-name, you may know him as "Dr. Figaro Newton" (from punch card).
Flashback ends here.
