I loved seeing the JLA and JSA working together even if they were arguing, but Clark brought them together. He will be the great facilitator, because he hates fighting with friends and he hates to see his friends fighting amongst themselves! He really keeps the Justice League together in comicsverse and ‘toonverse, too.
I loved Clark in this scene so much!
Actually, I loved Clark in all the episode! :)

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?
I really hope she knows.

I'm glad you enjoyed the episode.
I think this is one of the best (if not the best) episodes of Smallville I've ever seen. :)
