I promise you that I wouldn't have classified this story as creepy!fic if thoughts are all that happens. Remember, though, that Draco doesn't really know himself. He knew he wanted revenge, but had no idea what it would be until the last few chapters. So he thinks he's completely serious with his thoughts of murdering and consuming Harry, but on the other hand, he's also serious about his thoughts of going on with his life after his revenge- which he certainly could not do if he murdered Harry. Ron, in particular, would never permit that to happen.

So, at this point, Draco is completely wrong about himself as well as Harry. Or, when he sees a glimpse of the truth, he twists it around. He might be falling in love, but he's still going to twist those "revelations" toward the pattern of his obsessive interaction with Harry.

This story is largely about obsession and awakening from it.
