Poor Clark, but it's good that he's now ready to talk and that he's making progress, even though it's painful, and I'm glad he knows how good the other Clark has been to them and needs to be thanked.
I also wonder how much Lois knows about the other Clark’s past/world. Knowing would definitely demonstrate even more how amazing he is.
And if Jonathan knew.....
I bet that might snap some sense into him....
