This is great! The hint that something inside of Harry has changed, that infact his potion is removing something else is a great foreshadow technique! ^^ *loves foreshadowing, cause then can reread and be all like OOOOOOH I get it now!*

I have a feeling that what Harry hates the most about himself right now, is not his lack of control over his emotions and magic, but his lack of ability to protect Draco - which means his potion would work to increase his ability to protect Draco, which would in turn do his magical mumbojumbo that's been going on *bounces up and down excitedly* Am I right??
