Since no one was around and he was quite parched from his long walk...
He moved over to the bar and hopped up to sit on it, searching out the most appealing bottle within arms reach. "Hey, kid, you want a drink?" he called over his shoulder.
Now, Jiraiya had spent almost his entire life watching people. It was a paranoid habit, a hobby, and a skill he had honed to perfection. Unfortunately, he had very little sixth sense when it came to being watched himself. Something was nagging at him though. A tiny sensation that made him sincerely wish he had a pair of eyes in the back of his head.
Jiraiya remembered that there was a hole in the ceiling above the bar and looked up, fully expecting to see a pissed off Kisame grinning down at him. Then, quite suddenly, his wish came true after a fashion. His eyes went through the back of his head. Or, you know, what was left of them. It didn't even hurt after the initial shock-wave of agony. He didn't even really register the bang.
Three seconds of clear, concise thought later, he was panicking. He'd seen brains before, hell, he'd stepped in them, but those were his brains! He was staring down at his own dead body! He knew exactly how much blood was in a person, but there was no way that much blood could come out of someone's head! It didn't even dawn on him that it wasn't just the blood in his head that was pooling on the floor behind the counter. "I'm still breathing!" He tried to do the common sense thing and prop his legs up but his fingers just went right through his leg...and the floor and then he realized...
...his face was gone.
He screamed. He hadn't screamed like that since he'd woken up in the hospital with the news that Orochimaru had actually just beaten him to the edge of death and gone missing-nin. He screamed and tried desperately to help himself but all his attempts were met with the resistance of thin air.
