My major quibble with the story - what the hell happened to the mooks that Una shot with an arrow? It was jarring, particularly because soon thereafter M'Benga made a comment about having to fix things "before anyone gets hurt." I hate hate hate the "disposable extra" trope in Trek. Just because we don't know the names of the random crewmen doesn't mean their lives do not matter to the named characters.
Getting shot by an arrow does not necessarily mean death. Just because we don’t see them escape doesn’t mean they didn’t.
