This whole concept of an 'original timeline' is stupid. There IS no such thing as an 'original timeline' because after something has been done in the timeline to affect it in the future, time has changed, universes have split off, but there is no *original timeline* that continues flowing in a preset movement below all that. You change it, and for all the people in that relative timeline have just known that as the only way events played out, or indeed, would have played out. The myriad possible events that happen every moment all coalecse into seperate universes. How can you label ANY of them as the *original timeline*?
We really should debunk this flawed theory, if we hope to maintain the integrity of the Chrono universe, and at least be a little more respected as scientifically accurate within the gaming community. (The chrono one at least).
