You're stuck, remember? You wanted to be left alone. Ha ha ha!
~ Anirbas to Sabrina before vanishing away
Anirbas ("Sabrina" spelled backwards) is the villainess from "Sabrina Through the Looking Glass", episode 1.14 of Sabrina, the Teenage Witch. She is Sabrina's evil counterpart in the Mirror World, and talks to Sabrina, who is in a terrible mood. Sabrina's mood is so bad that she wanted to be left alone, and it was at that moment that Anirbas talked Sabrina into entering her world, through the looking glass for a moment of "quiet reflection."
However, Sabrina was unaware that the evil Anirbas was tricking her into remaining in her own bad mood, and she doesn't learn this until after she wakes up from her brief nap and attempts to go through the mirror, but fails.
Anirbas laughed evilly at Sabrina, while taunting her by reminding her that she wanted to be left alone, before fading away over dark clouds. The episode ends well for Sabrina, as she is able to escape her own bad mood.
As for Anirbas, she watches Sabrina constantly change clothes before walking away in frustration.
Melissa Joan Hart (who starred as the title character) played Anirbas, one of two villainous characters she played on the series. She later played Sabrina's evil twin sister, Katrina Spellman in three episodes of the series.
