In Season 5 of Pretty Little Liars, there were plenty of new bad guys that the girls had to face. And in one episode, when Shana shows up to supposedly kill all the girls in an empty auditorium, she instead meets her own end. While Shana was working with both Jenna and Melissa to target the girls, she went rogue when she showed up in a hoodie and a gun, ready to kill.
"Jenna doesn't even know I'm here, and she'll never know," Shana says, pointing the gun at Spencer, Hanna, Emily, and Alison. "And once I'm done with you, she can finally get back to her life," Shana adds, pointing the gun directly towards Ali while Aria sneaks behind her. Aria then attacks Shana with a stage prop and she falls off the stage, dead. Clearly, Shana had some pretty evil intent in those last moments, and her final words were exactly what you would expect from a villain.
