A repeated image shows the girl leaning into the pig's floppy ear and whispering to calm her down. We never hear exactly what she's whispering, but the tight closeups of Okja's mesmerized eye show us that she's listening intently and gets the gist—that the girl's words matter and make sense even though they don't speak the same language. The pig trusts her friend. All the film's many threads ultimately come back to questions of trust: what it means to keep it or betray trust, and whether there are circumstances where betrayal is necessary, and whether the trust between human and human is more meaningful than the trust between human and animal. Mija would tell you there's no difference.
