>Plot comments:
>
>The Phyllosians speak of encountering humans before, which is why
>they're able to cure Sulu; presumably they mean Keniclius, although
>the connection is never made explicit. Keniclius, of course, did not
>bother telling Starfleet of his discovery.

>The plague occurred when Agmar was "very young," an indeterminate time
>before.

>
>The background plates or cels against which the (somewhat)
>animated Swooper is moving. I'm going from ignorance, here, but
>I'm guessing they were mostly green, and that the animators
>didn't want the action element of the Swoopers to be lost among
>the greens, so they chose a contrasting color, one that wouldn't
>clash with green.
