It took me a minute to recall when in the episode Clark said those words, but by the time I had gotten to Lois's part, I had figured it out.
You do a terrific way of describing how 'never being alone' is a good thing to Clark -- all positives. It got me to thinking if there was a part of him that could be terrified by that possibility, too. You had him daydreaming about a relationship with Lois AFTER he had told her everything, but since he hadn't told her his secret at this point -- that even though he fantasized about the dream, I could see him also see that dream being shattered by telling her.
Never being alone means that Lois could see him floating in his sleep, so that he would have to be careful about sleeping in her presence before he told her. Never being alone was acting human 24/7, and never ever getting a chance to just be himself. Never being alone meant more lame excuses to duck out to do a Superman rescue, which Lois would surely know were lame excuses leading to Clark hurting Lois. Anyway, that's where it led my thoughts.
Lois certainly feels the pull in two directions. The way she expects she should act and the way she'd like to act... and rarely do the two cross let alone meet. It's as if Clark has opened her eyes to the possibility that a relationship and/or marriage could be a good thing.
I liked the dichotomy of their perspectives and thoughts on that same line.
