I thought so too. clearly it was Voldemort, or Voldermort's soul, he was no longer with Harry, it was just Harry from that point on.
just remember how Voldemort looked like in the fourth book,before regaining a body:
"Cedric's body was lying some twenty feet away. Some way beyond him, glinting
in the starlight, lay the Triwizard Cup. Harry's wand was on the ground at Cedric's
feet. The bundle of robes that Harry had thought was a baby was close by, at the
foot of the grave. It seemed to be stirring fretfully. Harry watched it, and his scar seared with pain again . . . and he suddenly knew that he didn't want to see what
was in those robes ... he didn't want that bundle opened....
....Wormtail pulled open the robes on the ground, revealing what was inside them,
and Harry let out a yell that was strangled in the wad of material blocking his
mouth.
It was as though Wormtail had flipped over a stone and revealed something ugly,
slimy, and blind - but worse, a hundred times worse. The thing Wormtail had been
carrying had the shape of a crouched human child, except that Harry had never
seen anything less like a child. It was hairless and scaly-looking, a dark, raw,
reddish black. Its arms and legs were thin and feeble, and its face - no child alive
ever had a face like that - flat and snakelike, with gleaming red eyes."
why King's Cross? I think that's pretty clear too: it is sort of like a Crossroad, a decision he has to make, whether move on to the next life (board a train)or come back to life and finished everything 8get out of the station).
"“Oh yes.” Dumbledore smiled at him. “We are in King’s Cross, you say?
I think that if you decided not to go back, you would be able to . . . let’s say
. . . board a train.”
“And where would it take me?”
“On,” said Dumbledore simply. ....
... “I think,” said Dumbledore, ”that if you choose to return, there is a chance
that he may be finished for good. I cannot promise it. But I know this, Harry,
that you have less to fear from returning here than he does.”
