Double Doors

Does anyone else notice that the Dumbledore with the Blackened Hand seemed somewhat 'ooc' from the Headmaster in the previous books?

Ok, granted, it could have been because he knew he was dying, or something, but what if it was something else?

Speculation is rampant right now, on the use of TimeTurners.. or whether or not there is one or two Dumbledores. Is there really an Aberforth AND an Albus? Much discussion on some quirks.

In CoS, she says that Harry saw "a fifty-year-younger Dumbledore", in Tom's memory in the diary. It tells that he had auburn hair and beard.

In HBP, she says that "This younger Albus Dumbledore had auburn hair." This was during the pensieve of the memory of meeting Tom.

In the first case, we are led to believe it is Albus, the current Headmaster, who is being talked about. He was Transfiguration Professor, so we believe that that is who Harry sees.

Likewise, in HBP, she calls him 'Dumbledore' throughout the whole chapter. No honorifics.... and then describes him as Albus the younger.

Is it possible for Albus to take on different images? Like a metamorphmagus? This persona is Albus, and that one is Aberforth.... or something different.

It may all come to nothing, but there is something odd with the whole thing... so I thought I'd jot it down.

Goes back then too... to Tom and Rubeus being on first name basis. The pensieve shows reality.
Not what we remember. So Riddle and Hagrid were indeed friends or something.

More later!
EDIT, on April 26.... I want to add that on a re-read, I noticed that when DD went to shake hands with Tom, the first time, in the orphanage.... Tom hesitated. I think he could see the 'memory' DD all along, and was freaked out about the burnt hand. I think Tom was 'looking between both of Dumbledore's eyes all right... again though.. not the younger DD's two eyes.. but the eyes of each Dumbledore... I know,... the apostrophe should be in a different spot, but I still think so. There are many clues to see, if you imagine that the 11 year old TR could see everyone present. He might have really wondered about seeing Harry... who looks like him somewhat.
