Did you guys watch the last episode?

Spoiler alert : Andrea is bitten. Rick hands Andrea the colt. Then Rick is shown standing outside the closed door and you hear a shot - and then something that bothers me - you hear a shell hit the floor! Since when do revolvers eject cases after a shot? You would think that you would hear a thud from the gun hitting the ground. Nope. It's clearly the sound of an empty case hitting a concrete floor. Amateur sound guys.....
