If you were talking JL, tt or whatever, know that I was not. Chronos doesn't have to be beaten by time travellers.

As for how, I've covered that with you almost as many times as you bring up time travel being required to fix impulse's timeline (ie; everytime impulse's timeline is brought up). They just need to change it from being changed, my theory being that the Reach are chrono-sentient at minimum. Your solution simply has too many logistical issues.
