Ack. The pain is just so palpable - Clark's numbness after Alicia's death, Lex's cold hurt at being rebuffed ... and that last line is a killer. I could really see it happening. Clark's being an ass, but his behavior is, I think, v. understandable. It always bothered me that TPTB never bothered to have Lex checking up with Clark after his ex-wife's death.
