So Lois has been sleeping at Clark's apartment for at least a couple of weeks at this point, and they both acknowledge that they are a couple and don't view their sexual encounter as a mistake. So why is Clark still sleeping on the couch? Why aren't they sharing the bed, even if they aren't having sex every night? This part depicts them as a committed couple, so why is there a damper on that facet of their relationship?
I like that Lois treated Superman as a friend - there didn't seem to be any hero-worship or romantic feelings directed in his direction. That should really give Clark more of an incentive to reveal his secret - he can't believe that Lois doesn't have feelings for Clark in this situation.
Definitely looking forward to the next part.
