Martha and Jonathan care. I wonder if Clark has ever told them what happened. It doesn't sound as if he's talked to anyone about this major trauma in his life.
And to cut himself off from touch... that's so wrong of him. He's definitely got the crazy thinking going on.
Hopefully, being around Lois will re-set his compass. And I'm glad he left the locket closed.
And won't Lois wonder why the locket was painted?
