While a bit tedious, this chapter was fillng. Dumbledore's explnation as to the 'unforgivables' sounds much like Yoda. 'Once you step down th dark path, forever will it dominate your destiny!"
Whether that is true or not, is in the future, however, Dumbledore's threat to Harry is clear.
'Either you do as I say, or this will become public knowledge!'
Fawkes' visible rejection of Dudley was funny! I think I read something of the sort elsewhere.
Petunia's rant makes a lot of sense, in many ways. Most see her as only a vindictive and cruel woman with no love to spare. Still, As an adult, she should have been able to put aside her hurt, for Harry's good. I have to take a great deal of shit on my job, but I don't bring it home. Nor do I retaliate in kind. That way, lies the unemployment line.
Any loving person would be proud to take in her sister's child, regardless the circumstance.
As before, I await the next chapter of 'Heir of Gryffindor'. Alorkin
