I'm glad to see we're on the same page :D. I think it's pretty much a concensus that this was one of, if not THE best episode of Smallville.

And when Lois said, “Clark!” after the kiss, was it because she knows it’s Clark, or is thinking how she thought badly of him after being tricked by Zod?


You have to ask? Lois has Mad Kiss-Identifying Skillz. It's canon thanks to Hydro and Crimson.
