Charmed stars gather to play Grey’s Anatomy sisters

It’s Grey Sloan Memorial, if any place ever required the Charmed Ones ‘ assistance. And it’s going to get just that… in a manner on October 7.

ABC announced on Monday the lineup for its special “Cast from the Past” week, during which various cast members and creative teams will gather in new ABC Shows episodes. Grey’s Anatomy will feature a Charmed meeting in season 16 when guest stars Alyssa Milano and Holly Marie Combs (as seen above) are sisters of a patient in the hospital who is brain dead after falling into a building site. They must then decide to maintain their sister alive. (No, their sister is not played by Shannen Doherty or Rose McGowan.) Milano and Combs played on Charmed for eight seasons with Phoebe and Piper Halliwell, two of the magical Power of Three. Doherty starred as Prue Halliwell for the first three seasons, but McGowan entered the show as a new half-sister Paige Matthews when her character died in the final of season 3.

Now, not only will Grey meet Milano and Combs on screen, but they will also be reunited with executive producers from Grey, Krista Vernoff and Andy Reaser, both of whom wrote on Charmed.
