Confusion

"'She said our art's important, and 'not just because it's evidence.'" Pg. 108

   When I think of the situation Tommy is in during chapter nine, I am struck by the number of directions in which he is being pulled. He has just broken up with Ruth and would undoubtedly like to reconcile the relationship. Then Miss Lucy comes along and tells him that despite his maturation, he needs to be concerned with his art once again-something that caused him great ridicule in years past. Tommy definitely feels as though this issue has passed. He became much more stable once he reserved himself to the fact that his art did not define his character. As far as Tommy was concerned, he was focused on choosing smart relationships towards the end of his time at Hailsham. Miss Lucy's words must also have been confusing for Kathy as well. As she herself said, Tommy was still not the most mature student at Hailsham. Why then should Miss Lucy entrust him with such profound revelations? What did she mean by "evidence?"
Clearly Miss Lucy saw it as a moral obligation to give Tommy this clue. Then she was gone.
