Sometimes it's a combination of both. But he's not gone, exactly, he's just not tracking well, and he eventually figures out the cigarette pack when his hand touches it. He takes it with a mumbled something that's supposed to be thanks, takes one out, and takes a very long, peaceful minute just to light it, draw on it, and let it out. Draw...and let it out. Several more times, just concentrating on the cigarette, until he realizes Leo's back with water.

"Oh...thanks." Taking the water and downing half of it in one go. "I...think so." He's doing better. Just...a little embarrased, now.
