I find it really interesting how Clark has two big secrets in this story. We're all accustomed to stories where we're trying to figure out when Lois will figure out the alien thing, but this time I'm more invested in his current situation and how he got here. I have a suspicion that by the time she figures it out, they may be so far along in their friendship that she somehow just takes it in stride, as the obvious answer to all the little mysteries, but I'm eager to see the journey.
