So the timeline is restored but the question I always ask myself is whether that alternate timeline which was changed back to the original one. Does that alternate timeline still exist? Is it another thread and another possible universe that has always been? Or has it been forever terminated?

Since you write a lot about time travel I wonder if you have the answers to those questions?

Author's Response:

I'm of two minds about this. In the other story I submitted for review, a character claims that there's only one timeline to a customer. But that is absolutely not true in Trek. I think alternates like as seen in the TNG Parallels episode would indicate that the altered line still exists, somehow, somewhere. And maybe the otric changes aren't so otric after all.
