As she began her sophomore year, Lana prepared a video of well-wishes from his friends back home to send to Whitney, but then decided that she should be honest with him. She recorded her own message, breaking up with Whitney. Whitney wrote a letter to Lana in response to the videotape. He mentioned the pain he felt when receiving the message and said it was a truth that he didn't want to hear. But Whitney decided to let go and told her that he was glad she was looking for happiness and hoped that she'd find it.
Whitney was later announced as missing. Tina Greer broke out of Belle Reve Sanitarium and impersonated him in order to be with Lana, but Clark discovered the truth and she was killed in the final confrontation.
Both Clark and Lana were deeply affected by Whitney's death: Lana regretted ever having sent the video to him in the first place and feared that Whitney's last thought before he died was that Lana wasn't there for him and Clark remarked that Whitney had willingly put himself in harm's way to protect other people and wondered if he would have such bravery if he didn't have his abilities.
