After he watches Four-Eyes forcibly ushered into the sinister black car that's waiting, Sasha wonders why anyone would admit something they were not guilty of.
Cue up the Sasha Imaginarium Music. He imagines Four-Eyes walking up to the prison where he is given standard prison-issue striped pajamas and put into a cell. He wonders if Four-Eyes will see his (Four-Eyes's) father, and thinks that he might like to see such a reunion.
And then it dawns on Sasha: Four-Eyes admitted to a crime he did not commit because it was a way to get inside the prison to try to see his family.
This seems to make Sasha feel better, and he kind of praises himself for having a hand in getting Four-Eyes into the prison. He imagines that Four-Eyes will be super happy to get to have a good, old-fashioned Lubyanka prison family reunion. He even wonders if there are family cells in the prison. Hey, there's a sunny side to every street.
Things are looking up for Sasha. He's back on track to becoming a Pioneer, and is confident that he'll see his dad soon.
But Vovka pops his shiny happy little bubble by pointing out, totes sarcastically, that a Young Soviet Pioneer lets others take the blame.
