Uh... because there aren't any other time-lines where Goku wasn't given the medication?
Haha, now it
your turn to read

It's a bit jumbled, but I think you should be able to understand that that Goku's given the medicine twice. Arrows are helpful
It means that, up until the time-line split while Trunks was in the past, there was only one time-traveling Trunks. Just like, until Trunks made his changes one his trip back, there was only one Cyborg Freeza, one Goku, one Gohan, etc. The are exactly the same person because there isn't two of them until the time-lines diverge. Then he gets 'split' into two people. Same as how Bulma was split into two and existed both in the past time-line and in Trunks on Future. Trunks now eixsts in the past time-line without Cell and in the past time-line with Cell.
I'm not sure what your getting at... are you trying to say that someone split the timeline while Future Trunks was in the past? Like , Trunks timejumps back in time (splits from his timeline to a second one) then someone else timejumps to that timeline creating another timeline (one with the new guy and Trunks, the other with just Trunks)?
That would be a good explaination on how there would only be one apocolyptice future but two future Trunks (one who kills Cell, one who get's killed by Cell).
Of course, there's no way that could have happened. There would need to be either someone else with a time machine, or Trunks would have had to travel back in time to a point where he was already there. Not that either of those events are impossible - they just didn't happen.
Ok, so you're saying that Cell goes back in time, appears in the past, and for some odd and unexplained reason, just lays in the ground for all of eternity, never to appear,
No, I've said at least twice in this thread that he could have been killed by either #16 (who stated he was stronger than first form Cell) or #17 and #18 durring their rampage. Though 'just staying in the ground' isn't impossible either (just kinda lame).
He didn't emerge until Trunks traveled back in time again, so perhaps it was just some weird 'chaos theory' effect from that.
WHY does he appear in the Time-line that Trunks appears in, then?
Um, you mean 'why does cell emerge from the ground, become perfect, and host the Cell games in the timeline we see in the anime'? Well, he
does. We 'see it in the anime'.
There is absolutely NOTHING to this theory...
Someone's starting to hurt my feelings :'(
Seriously, this would be like saying that you sent a bomb back in time but it never went off.
Sigh... maybe it
didn't go off. You completely disregard the idea that it couldn't. Why couldn't it just NOT go off?
So you went back to find out why and it goes off before you even did anything. It's not possible. Hence the flaw to your theory. Which is an even worse flaw than the one I *thought* you had... wow.
Wow, now you're just being a jerk. I've been really good about saying you've just 'misunderstood' or 'misread' things - now I'm pretty sure you're just stupid. I say 'A because of B' and then you say 'why does A happen? that's stupid'. Now I've already explained it, and you just don't understand.
The rest of us are being rather nice to each other, you could at least be
civil.
If you have a problem with my theory, ask a question, I'll answer it. If you think I'm wrong about something, tell me and I'll explain better, and if I can't:
good that means we're moving forward and are improving the theory.
Just to explain this ONE MORE TIME...
