As I was watching Dead Things, I noticed an exteme similarity between the scene with Buffy and Spike on the balcony and Buffy and the Master in Prophecy Girl.
It's mostly the imagery (actor placement, Buffy in white, Master/Spike in black), but there's also something to the mood and the fact that they're both so intent on defining her (The Master: "You still don't understand your part in all this, do you? You are not the hunter. You are the lamb." vs. Spike: "That's not your world. You belong in the shadows... with me.") and proving that they're the ones in control.
Also, I don't think the Master, you know, put his hand up her skirt. Then again, I think I saw a fic once that may very well disagree.
