Annemehr:

I like the plot you propose, and I too wonder how a rebounded AK could
transfer anything from Voldemort to Harry.  I'm also quite sure we
know very little of what actually happened that night.  But, I just
found the passage that I always assumed referred to Voldemort's
attempt to AK Harry.  It's at the end of PS/SS ch. 2, when Harry is
trying to remember the "car crash" that killed his parents and gave
him his scar:

"Sometimes, when he strained his memory during long hours in his
cupboard, he came up with a strange vision: a blinding flash of green
light and a burning pain on his forehead.  This, he supposed, was the
crash, though he couldn't imagine where all the green light came from."

Harry having mentioned his dreams about flying motorcycles earlier in
the chapter establishes that he does indeed have some memory of that
time, so I am inclined to trust this vision.  To me, a "blinding
flash" of green light has to be Avada Kedavra headed straight for your
head; otherwise it's merely a jet of light.  Besides, the pain in his
forehead is associated with it.

In PoA, when the dementors and boggart!dementors are around, there are
only sounds; I can't find any reference to green light.  Besides, when
Lily took Harry and ran with him that night, I can easily imagine that
she put him in his room and shut the door, and stood outside to face
Voldemort.  There's nothing in the books that says Harry saw her death
at all.

So, I can't get around it.  The green light is associated with the
pain in Harry's forehead and the scar, and the scar is associated with
the connection to LV.

One loophole left, though, maybe!  Okay, so the AK rebounds and
unbodies Voldemort.  Though I doubted it before, Phil (congusinglyso)
could still be right that the SuddenlyVapor!Mort tried to possess
Harry; except that rather than Hagrid taking Harry!Mort to be
separated, Voldemort found himself repelled right away, by means of
the new scar, leaving a bit of himself behind in Harry.

Could be, could be.  I won't bet the house, though!  ;-)
