Bill awoke by some commotion, and the fact that he was being pushed out of the couch to make place for a wounded man. Tired, unknowing of any previous events and grumpy about being woken up and having to get up, Bill's short fuse was nearly non-existant now.
John, of course, tried to reason with the man. Patch him up, feed him, talk with him, generally being the nice guy again. The nice guy in a world full of psychos, how did he ever survive. Bill rolled his eyes at John's comment.
Then Alexia spoke her mind. Not necessarily for everyone to hear, but Bill was close enough to hear her silent protest. That idea sounded so very much better to Bill. A clean shot between the eyes, would put the man out of his misery. From what Bill heard from his shouts, he was mental anyway, no need to keep a danger alive if you can remove it before it strikes.
A satisfied grin tugged at Bill's mouth, showing his teeth as he pulled ol' Daisy from her holster. "Sleep tight." He said, put the barrel between the man's eyes, then fired without a moment of hesitation. John, who was pushing against the man's shoulder, got blood splattered against him.
As he turned away from the man, Bill spun the revolver around his finger, before dropping it into the holster. "That takes care of that."
