The Conditional That Would Not Die

OK. We're currently at the head of the "moaning" narrative.
 We need to play that.

        --
        -- do the "moaning" branch
        --
        rc = narrator:play(stage)               -- run it
        assert_true(rc)                         -- not done yet
        assert_equal(2, stage:num_oq())         -- two items in output queue
        assert_equal("text", stage:oq(1).type)
        assert_equal(                           -- using [[]] to escape " chars
                [["Moan! Moan, moan, moan! Moan!"]],
                stage:oq(1).value
        )
        assert_equal("text", stage:oq(2).type)
        assert_equal(                                   -- second snippet
                "The door remains unmoved",
                stage:oq(2).value
        )
        assert_nil(narrator.userdata.moan)              -- still not set
        assert_equal("moaning", narrator.narrative.name)-- same narrative


And that all passes. Play again for the func and the jump. This may look
familiar

        --
        -- play it again - this will run the func and the jump
        --
        rc = narrator:play(stage)
        assert_true(rc)
        assert_true(narrator.userdata.moan)             -- now it's set!
        assert_equal(                                   -- new narrative
                "in_the_room", narrator.narrative.name
        )
        assert_equal(0, narrator.index)                 -- index rewound


and that passes. Now for the final loop


        rc = narrator:play(stage)
        assert_true(rc)

        assert_equal(2, stage:num_oq())
        assert_equal("text", stage:oq(1).type)
        assert_equal(
                "You don't like it in this room. What do you want to do?",
                stage:oq(1).value
        )

        local options = stage:oq(2).options
        assert_not_nil(options)
        assert_equal(3, #options)

        assert_equal("Sulk", options[1].text)
        assert_equal("sulking", options[1].next)
        assert_equal("Complain", options[2].text)
        assert_equal("moaning", options[2].next)
        assert_equal("Try The Door", options[3].text)
        assert_equal("thinking", options[3].next)


And that works! So option three shows up! I suppose I'd better make sure it works as a choice should...
