Of course, one time-line he has - the one where Lois didn't make it. And in at least one other Superman may or may not make an appearance
But when they go back and fix things doesn't those timelines cease to exist? I mean, when they went back and made sure Lois survived, didn't that timeline (the one where she died) disappear?
If all the timelines keep on existing, so the timeline where Ellen, Lucy and Dave died will be maintained. It means Lois and Clark disappeared overnight in that timeline and left Christopher and Nate orphans!
If each change is creating new timelines (instead of fixing their timeline) Lois and Clark will be living in a new timeline that isn't the one where they belong and there will be no Lois and Clark in their timeline. Isn't it?
Does somebody understand what I'm babbling about?
Ugh... the room is spinning. My head hurts...
Time travel is a very confused subject.
