Worlds are soon colliding on Netflix with the reveal that Chilling Adventures of Sabrina is bringing in two of the stars of the original Sabrina the Teenage Witch TV series adaptation. Developed for television by Roberto Aguirre-Sacasa, Chilling Adventures of Sabrina is a fresh take on the source material that previously had no connections to the original ABC series. That all changes as seen in a sneak peek video of Netflix show's fourth and final season, revealing the original Spellman aunties meeting the new Sabrina.

In the clip, we can see Sabrina, the Teenage Witch stars Caroline Rhea and Beth Broderick both reprising their old roles as the original Hilda and Zelda Spellman. Somehow, the two Sabrina universes have started to merge, breaking the fourth wall as Sabrina (Kiernan Shipka) even takes notice of an audible laugh track. Amidst utter confusion, Sabrina asks Hilda and Zelda to introduce themselves, only to learn that they're an alternate version of her aunties. It would appear the teenage witch has found herself in some time paradox.

Chilling Adventures of Sabrina antagonist Father Blackwood (Richard Coyle) is also featured in the clip, assuming the role of the "director" of the sitcom world Sabrina has found herself thrust into. He seems to be much more familiar with the bizarre situation that's unfolding, assuring Sabrina that she'll catch on quickly to what's happening. Time will tell if this means Blackwood is in control of the situation or if he's just as much trapped in the paradox as Sabrina. In any case, fans of the franchise are very intrigued.

Created by Nell Scovell, Sabrina the Teenage Witch premiered on ABC in 1996, ultimately running for seven seasons and spawning a handful of TV movies. Melissa Joan Hart led the series as Sabrina Spellman, a teenager living with her 600-year-old witch aunts (Rhea and Broderick). The sitcom is also memorable for featuring Salem as a talking cat, voiced by Nick Bakay. As of now, there's no indication that either Hart or the talking Salem will also appear in the upcoming crossover, so let's keep our fingers crossed.

Debuting on Netflix in 2018, Chilling Adventures of Sabrina quickly managed to find its own audience with viewers, even with a drastically different tone that's much, much darker than the comedy series. Like the other TV series, the new Sabrina includes Hilda and Zelda, this time played by Lucy Davis and Miranda Otto. Salem has a strong presence in the new show as well, though he doesn't talk or make wisecracks in this version. The series also stars Ross Lynch, Michelle Gomez, Chance Perdomo, Jaz Sinclair, Tati Gabrielle, and Richard Coyle.

Chilling Adventures of Sabrina will debut its fourth and final season on Dec. 31 on Netflix. In the meantime, whether you have yet to watch the series or if you just want to reacquaint yourself before the final episodes drop, you can currently binge all three seasons of the series on the streamer.The sneak peek clip featuring the return of the original aunties comes to us from Netflix on YouTube.
