Eric Bischoff: "So I think we need to get Joe off TV for a while, let him refresh his character a bit and come back strong. I'm not sure how to write him off TV though..."
Ed Ferrara: "Hmmm, how about we reveal that he was 'injured' at a recent house show?"
*Vince Russo enters room*
Vince Russo: "Hey guys, how's it going?"
Eric Bischoff: "Fine, we're just trying to figure out how to write Samoa Joe off TV for a while, I think he needs to refresh his character"
Vince Russo: "Why don't we have him get kidnapped by ninjas?"
Eric Bischoff: "That sounds ok, but then how do we bring him back?"
Vince Russo: "Lets just run the angle and we'll worry about that later"
The above is a dramatization of a typical TNA creative meeting, illustrating how the writers decided to go with an angle without figuring out how to justify it. Nobody knows what happened with Joe's "kidnappers", and since the writers never bothered to come up with a reason, nobody ever will.
