- we still didn't get to see what's inside; - there is actually no direct evidence that the person being vaguely threatened is Nia; she is the most likely one, yes, but since this is the time for revealations, we may find out something new about Chief; - why do we see this? maybe Kamina will be shown listening in to the scene next time and it will be a giant plot-driving dramatically ironic misunderstanding; - Rossiu had performed the slimy manipulating douche routine admirably! Kudos captain!
As much as I'm one of the few people who like Rossiu, I want Simon to have him grit his teeth so that he doesn't have to wear dentures as a result of of getting his ass beat. You don't threaten Nia. We all have seen what happened when someone threatens Nia. Take it back Rossiu while you still have time and teeth.
