Another episode means another day in prison for Cassian Andor (Diego Luna), who's still being held at the Imperial facility where he's forced to work for basically an indefinite period of time against his will. With the Empire changing inmates' sentences with no real rhyme or reason, Andor's starting to become a bit more fearful as the days go on.
While outwardly, it might not appear as though any cracks are forming at the prison, if you look close enough, they're just barely starting to appear. Even the smallest of cracks eventually give way to something much larger, and in this case, it looks like there might be a good 'ole prison uprising in Andor's future.
