He gets up again - sort of, pivots around, kneels up, grabs the bottle and passes it across to Jack. "I can understand why," he says, with nothing but sympathy.

He's not personalizing it at all - because it's not him, and there's no actual evidence that there is - but there's plenty of proof that this guy? Is hurting like hell. He is still him, still better for being with the Doctor, and compassion and love are as much part of his personality as charm, manipulation, and sex.

"It makes the TARDIS make sense, though. Moving around - wouldn't fix it, but it has to be better than being stuck." Absolute warmth, concern, and compassion, still. Almost gentle.

And enough so, that he's making mental notes to offer to clean up this mess while Jack showers. Once Jack's a little less shattered, looking.
