I'm really kinda speechless, so I'll just add a ditto to some of the other wonderful comments I read through, especially the first one. It was just the perfect representation of what happens when you're just too exhausted and you have to let go. So I'm in a slightly gooey grin of Clark being able to be there for Lois while she lets go of a side of her most people don't see.
