I decided to allow some time to post my comments for the last episode, which I've finally watched on yesterday.
In regards to
Shiroth's comment at the
Pandora Hearts thread, I agree as well that for an anime-original ending it was flawlessly executed; a rarity since fillers and anime-only content generally tend to suck.
My only complain was that Ash/Angela's overall goal limited "his" potential only to a megalomaniacal scheme to purify the world in a contrasting manner to Noah's Great Flood (by fire instead of rain).
What intrigued me was that this episode drew a distinction between the demons (Sebastian) and the angel (Ash/Angela) not to their opposing nature and neither to the biblical context of good versus evil, but....
The only other complaint, though a minor one, was that Ash after all never posed a real threat to Sebastian. I mean c'mon Sebastian raised the bet....
Spoiler:
By transforming into his true demonic self, and not even once Ash/Angela was able to give off a proper show to put a workout for Sebastian, at the least.
The most he became after Sebastian wasted him/her was dog fodder.
Sebastian deserved a more a foe of higher ranking, refined caliber, and of a taste worthy of Sebastian's own preference not some megalomaniacal, hermaphroditic, winged-pimp.
Anyways, done with that the epilogue that followed right after the climax battle left me in tears.
Spoiler:
It leaves in ambiguity whether the three servant stooges survive or not, although Sebastian informs Ciel that he heard them all breathing with difficulty.
We know that Pluto's dead, because the three servants pledged to the young Lord's order. A thing which Ciel briefly mourned over for another loss, whether needed or unnecessary.
At the end, Tanaka's whereabouts are left ambiguous. The elder butler just vanished off the Earth.
But we know where was Ciel heading, as the second ending video montage depicted.
Over that, I cried for Ciel the most. He had not regretted the decisions he made; the pact with Sebastian; the game he played and became victor; and dying.
But I think that Ciel's eyes giveaway a little of fear and anguish not much about delivering his soul to Sebastian to fulfill the last term of the contract, but because had he survived the game he would likely attempted to reap a little bit of a bright future as the late Aberlain encouraged him to do so. It's just that his time ran out and that path shut off.
However, I liked the way how Sebastian actually displayed kindness to Ciel.
Taking into account his former masters' feelings and the past incident at Eiffel Tower, he offered the young Lord to take his soul gently and with the least pain possible.
Of course, Ciel adamantly refused because he acknowledged that Sebastian fulfill his obligation from beginning to end. The most he could for his former servant was to pay him properly and not denying him his most basic nature's desire.
The irony of it all was that throughout the anime Ciel longed maliciously to witness Sebastian failed just once as a butler, and actually Sebastian admitted on the ride he couldn't become a perfect butler after having his left arm got torn off in the final battle.
And then the ending....
