You know, just because you spend a lot of time with someone doesn't mean you know their darkest secrets.
When Clark's old friend, Earl Jenkins, is found in the loft during an unsupervised and out of control party at the Kent Farm, Chloe goes with him to the hospital. Clark shares a very cute story with her about his trying to learn the guitar from Earl while they are waiting for the results. Once again, Chloe gives dialogue that "just because you spent a lot of time with someone, it doesn't mean you know their deepest, darkest secrets."
