I'm having a major OMG! moment. I just read the entire story and the audaciousness of it all leaves me speechless. I am still soaking it all in so I don’t have a feel for where it is going yet.

My read is that based on what Wells says, if he leaves things as they are, the universe will collapse. Personally, I see a split timeline.

1. Leave the Lois’s where they are any you have one kid of split.
2. Put them back and you have a different split.

Of course, you may put them back and the universe implodes anyway.

Finally, what if the switch makes everything worse instead of better? You might poof a perfectly good future just to have the alternate time line that overlays it be worse than the one you started with.

Time line meddling can be hazardous to your (and everyone else’s) health!
