It's About Time

What do you think was the original reason for Twilight to tell past Twilight not to panic? For more clarification what event could of caused Twilight Sparkle to use the time spell and start the loop?

@Dr Outback  
Despite the end of the episode being about nothing bad really happened, she still did a lot to prevent possible disasters in the episode like fixing a dam, so maybe one of these things happened the first time to start the cycle.

If that was was the the case then Twilight Sparkle being alarmed was a good thing.

I love Time Travel and i still don’t even this episode.

I think the original reason was to tell herself not to freak out, which she failed at, thus creating a stable time loop.

Loops have no beginning or end. It’s infinite.
 
To imply that there was a “first” loop implies Twilight is actually responsible for there being such a thing.
 
Like time itself, it was always there, and always will be.
 
You’re assuming the time line was originally linear, but was then altered into a loop. Why assume that?

@Frost above said it pretty well. :D
 
It’s pretty funny that even when it is demonstrated for you in the story how time travel works, you still try to cling on to this idea of events happening in linear progression. Old habits die hard, eh?

The above three posts got it.
 
Although personally I still don’t agree with the “no such thing as linear, cause-effect pattern” notion. You can still have that, it’s just something like:  
A cause makes an effect, which makes another cause, which makes an effect, which effects another effect, which effects a cause, which causes a cause to effect another effect, which effects the effects of a cause of the original cause in an effect to cause the effects of the cause.
 
You get the effect of what I’m saying? ‘Cause I ain’t gonna try to effect your understanding by effectively explaining further. That’d just cause a bad effect on this whole situation.

is it about time?

Still the real catastrophe event explain the situation in 2 out of 3 time travel theory, multiverses and a form of time erasing, when the permanent loop can only be explained by the probability of the future hapenning before the past in a non-linear time.
 
The last theory may seem support by the fact twilight go in past at the end, meaning that the future is written, as supported by this theory, but multiverses theory allow the possibility of a cycle between universes where all of them go alter the one that happen to be one week younger.
 
Time erasing on the other hand is supposed to cause the end of time in case of loop because the loop won’t allow the time go any further than the time travel moment but the way the spell work, the travelers go back to the future right after, mean time go on after a time travel and a stable loop can explain the timeline stability as the infinite time travels all end up with the same outcome and no world’s modification after the first, or at least a certain number of, loops. In this theory, future twilight experience the world changing the first time and maybe a few more but to save the worlds from being constantly alter by the unstable loop (a loop with different outcome but all of them include the initial time travel) making it impossible to have a coherent timeline after the time travels event, the loop can be both stabilized to a one outcome state or broken.
