interesting. The HarryFleur interaction was a bit too sappy, fairy-tale for me.
Two suggestions:
1 - try to avoid in-chapter author notes. They really break up the rhythm of the story.
2 - I noticed a bit too many exclamation marks. From what I have seen, they really shouldn't be used other than to emphasize dialogue (i.e, "Get away from her!") Exclamation marks in battle description tend to make me feel as if it is less mature writing. Periods do their job well; trust them.
Good chapter, try to lengthen them, as I enjoy longer chapters where I can really sit down and enjoy it.
Waiting for the next chapter, good luck writing!
