Brief reaction post only from me tonight. May do a longer one after watching it again.
Well - that was.... Um, yeah - Rusty's proved me right in a way I wish he hadn't done... Ten really has become a vengeful god (just as he told Jack would happen if a Time Lord took the power of the Vortex into him - which, uh, he did when Nine kissed Rose and took the power from her) - and now he's decided the Laws of Time are his playthings.
What impressed me was that Adelaide killed herself - that she refused to let him dictate her future and did what she felt was the right thing - that was a very brave decision to make.
