It's too bad they didn't figure this out until after Clark divorced Lana and married Lois.

But, would the Lois and Clark of the other universe have got divorced too? I would think that would be more complicated, because they have kids there.
Still, I find it hard to believe they would be comfortable being married anymore than OTOH Lois and Clark being married to Lana and engaged to Joe. On the Other Hand smile , their siginificant others in THAT universe are in love with other people by now. So they couldn't gravitate to them easily the way OTOH Lois and Clark did in the universe they were thrown into.
But that doesn't mean they didn't at least START divorce proceedings anyway.


On the Other Hand smile , the preview indicates the Clark that married Lana adapted to having children well, even if their not with Lana. (I suppose that makes sense, given how eager ANY Clark is to have kids.)
Would that mean he adapted to being married to Lois as well? I would think that would take a little longer than a few months. But still...
