Chloe and Clark were transported to the Fortress of Solitude in the Arctic and unable to withstand the sub-zero temperatures, she called out to Clark, who begged to interrupt his training to save her life. Clark took Chloe to a hospital in the Yukon and Chloe finally told Clark that she knew his secret and Clark told her that he is an alien. She became his confidante, promising to never be the "iceberg to his Titanic." Later, Lex located her and took her back to Smallville.
