A good part. I wonder, though, whether they would take the time to have that conversation and hug/kiss in the duct. I would think that their first priority would be to get back to "Lois' apartment" before she could be missed. Of course, if they were dawdling in the duct primarily so that Clark could rest from the exertion of getting them into the duct, that would be different.
Looking forward to the grand finale. (My guess: The almost-wedding proceeds pretty much as on the show, except that Lois expects that it will be interrupted by Perry et al. and starts to go through the motions of getting married just so that Lex won't get suspicious. She goes through with it up until the point where she would have to say, "I do," and realizes that she can keep the sham up no longer. Just as she breaks character and says she can't marry Lex, the cavalry comes crashing in to the rescue. I suppose it would be too soon into L&C's new relationship to have the wedding proceed with a new groom...)
Joy,
