Now that was quite an intriguing chapter and great fun. The description of the three gals was quite interesting and I chuckled over the description of Ginny's swimsuit (if she really wants to cause "glandular meltdown", there're some places on line that ones making that one look "conservative" - accentuating and emphasizing certain attributes rather than (barely) hiding them). The conversation 'tween Guinevere/Gabrielle and Hedwig was, literally, a hoot; it does make me wonder if magically communicating animals have special names for their humans the way David Weber has shown that Sphinxian treecats do in the "Honor Harrington" series (for ex. a very determined ruler is "Soul of Steel" and a very capable military leader/warrior who enjoys flying is "Dances with Clouds").
Luna's comments about the letter are quite amusing, esp. the one about what's "normal" for Harry.
The training procedes apace and I get the impression Harry's encountered another gal, the Lake Warden, who's very interested in training him in -every- way, including taking care of his ladies. I wonder of Harald Fafnersson will be come another alias for him? The first name is good, similar to his "regular" name, but with echoes of rulers like Harald Hardrada in it.
Finally, Ron seems to be divorced from reality and it apparently wasn't an amicable divorce. 'Twill be interesting to see the efforts to cure him and how he feels afterward; I know I'd be rather embarrassed.
