It's not pretty, but it certainly is powerful. This flashback to what Lois went through while she was missing certainly establishes that she's not our universe's Lois, and that she can't be expected to act or respond to things the way ours would. Alt-Clark knew a very different Lois for a very short amount of time, built fantasies in his head of what his Lois might be like based on that, and then abandoned those fantasies when he gave up hope of ever finding her alive. When this Lois comes into his life...well, I'm interested in reading what happens.
