Smallville - Season 7 Episode 13 -

Pete Ross returns to Smallville and finds a number of surprising changes since his departure four years earlier. Besides resolving his feelings toward Clark since he learned of his friend's secret, Pete has to deal with the acquisition of a superpower of his own: that of his ability to 'stretch' his body courtesy of kryptonite-laced gum he's been chewing and consuming for nearly a year. Meanwhile, Lex continues to sow seeds of anxiety into the amnesiac and powerless Kara over Clark as well as wanting to know about her past, as does Jimmy Olsen.
