S1, E11: Helena refuses to attend her high school reunion, not wishing to relive the past. But when Helena's visiting former classmates are murdered one by one, Barbara persuades her to get involved. The male victims were all seen aggressively flirting with Helena in the bar where she works, and the same man, Jack Barrett (Christopher Wiehl), defended her each time. Following clues, the women pursue a skillful killer with a chameleon-like ability to blend into his surroundings. Meanwhile, Helena copes with her romantic attraction to Jack and continues hiding her true identity from Reese.
