I hear this loud, computerised alarm sound bleeping! A voice is

Bruno - I want the job. I need the bloody job. I copped a redundancy  
from my last employer and I have been searching on "forced vacation"  
for over a year now for The Right Job. This global recession is real.

It would truly not surprise me if it turned up on Mars. If I want to  
"continue to put food on my family" as George Bush says, I guess I had  
better go pack my bags for the teleporter

I do. I even volunteer publicly to be the first person to be fully  
teleported from Sydney to Brussels to serrer Bruno à la main

So - I KNOW I'm not allowed to ask "what about the missing 4 minutes"


consider it "not asked" again

Will I, after reconstitution, experience continuity from prior to the  
4 minutes or the discontinuity of amnesia?

"Will I dream, Doctor?"

That is true but it all depends what you mean by "find"

On Sunday I also "found myself" on Earth.

How is this different to simply believing this to be true?

Both these statements mean the same thing to me

True for me, but watch out - maybe Bruno is a charlatan and the  
machine sends me to the Tax Office

As above

Yes, unless, like Borden and Angier in "The Prestige" we are secretly  
at war with each other and manipulating cleverly each's perception of  
the other

Bruno could KNOW Kim is really on Earth (in the Tax Office) and Kim on  
Mars might be a zombie re-programmed (during the 4 minutes) to respond  
"as if" it were the real Kim.  From the perspective of my job, the  
zombie does it brilliantly and get lots of bonuses and a brilliant  
career and all the while on Earth Bruno is able to double-tax my  
income and becomes a highly-paid public servant

> -On Monday, Kim feels himself to be now on planet Mars.

He does. Unless he is a non-conscious though nonetheless perfectly  
convincing zombie (with negative self-awareness)
