Jack regains consciousness with a shudder of life, and groans before he can stop himself. He pants heavily as he gets to his knees, looking around through blurring eyes - but Lisa doesn't seem to have seen.

He turns, eyes finally focusing and sees Ianto lying on the ground near him. He isn't moving. Jack's hands move almost of their own accord to pick the boy up out of the water, feeling the weight of an empty shell against his body and cradles it against him, feeling his throat and skin. There's a pulse there somewhere. He glances behind him as he hears Lisa's heavy footsteps somewhere above. There' not much time, but... He pats at the side of Ianto's face, trying to get him to wake up. There's barely a storring, and desperately Jack leans in to kiss him, willing heat and life into his limp body - not even sure why, only knowing that he doesn't want Ianto to die.

In spite of everything, he wants him to live. He can hear Lisa's slow, mechanical footsteps a little way away, searching for the others, but all that matter for now is forcing life into the stupid, lost boy in his arms.

And then there's a gasp against his lips, and the body jerks with awareness. Jack pulls back hastily.

"Ssh!" he insists urgently, and tugs him up off the soaked floor.
