Congrats on a 4th season can't wait to see it, now I have browsed the archive many times and since these questions weren't there, so I am assuming they haven't been asked
1. How big is the Timeline currently.
2. You said Earth-16 has some significanct relation with the number 16, I am assuming that means there's more to that then you all dropping 16 in every episode. If so how long do we have to wait is the answer only going to come when we reach season 16.
3. How concrete is the timeline like are their things in it which you thing can be subject to change or is it already vague aside from the necessary stuff i.e have you gone back and changed something thinking this has to better why didn't I think of this before.
