Someone is moving toward him. He sees them, in his peripheral vision, and stops walking. It's the Doctor. He's with a man he recognizes as Mark, from New York, and a woman with red hair who he doesn't know.
The Doctor looks shattered. He comes to stand in front of Jack, his expression one of disbelief and despair. The Time Lord moves the coat, looks at Rose, who appears bundled and safe and not dead at all.
The brown eyes look very old right now. Jack wishes her could fix things. He's let him down. He tried to save Rose and it didn't work and it should have worked, and now his friend has lost the woman he loves.
Jack licks cracked lips, feels a bone in his back mend as he's standing there, in the snow, holding Rose.
"I... tried..." he whispers. He hesitates, then lets the Doctor take Rose from him. Rose, who trusted Jack to keep her safe. Rose, who said she loved him despite his being some freak show feature. Jack sways a bit, still looking at the Doctor, unblinking, eyes dark navy blue. "We tried... " His voice breaks. He sinks to his knees, let's his hands drop into the snow, and stares at nothing.
