Never Seperate - S1.E35

Stacey calls and ambulance and her parents and everybody else except her and Donnie are shocked at Stacey's twin, as they have no idea of whom she is. Kendall cannot be revived, and after Stacey and Donnie go visit to the room, they find her disappeared from the room. They both run to the park that they found her, with a shattered mirror piece. Stacey stares into it, and sees Kendall, waving happily. As the sun goes down, Kendall's image fades, and says her lifeline is light, and that's why she lives with the sun, moon and stars. Sadly, Stacey doesn't want the sun to go down, because she won't see Kendall until morning, but Kendall says, the reason that Stacey can see her through reflections, is because she is part of Stacey, and is always inside of her in time of need. At the end, Stacey wraps up the mirror in her jacket, while Donnie escorts the cryig, lonely twin home, and promises her they'll get Kendall back
