What? No, you should be able to just plug in the password the fest mod left in the post, right under the embed (it's "watershed") and click play. Assuming you have the usual plugins and vid codecs installed on your machine.

Oh Captive Prince. It does start out completely WTF. I think I had the same reaction you did, back when it first crossed my radar: dipped in, backpedaled quickly. Later, princessofgeeks posted a, "Yay, CP has been updated! Squee!" in her journal, and I was bored, so I clicked her link to the latest chapter. And fell hard. Just stick it out (skim, skip around, whatever) until they get out of the palace, okay? About eight chapters in, it turns into a whole different animal, I promise.
