Shannen Doherty’s Charmed Costar Shares Details on Her 'Work Ethic' In Last Days

"We were lucky enough to record four episodes in the last week or so, and Shannen was just so motivated and determined to help make this show a success and give all of you more insight into what it was in the making and the fun and the behind-the-scenes of Charmed," her former costar and co-host Brian Krause said.

Shannen Doherty was busy at work in her final days.

On Monday, the actress' former Charmed co-star, Brian Krause, gave an emotional introduction to the re-launched House of Halliwell: A Charmed Rewatch Podcast -- which Doherty had just joined last week -- while reflecting on the shocking news of her death at age 53.

"I come to you this evening with a heavy heart after learning the news of Shannen Doherty's passing just yesterday afternoon," Krause said as he began the episode.

He continued, "I know all of us here at the House of Halliwell, iHeart media, social media, all over the world are shocked, devastated. Too young, too talented, too loving, too grateful, too early. Shannen will dearly be missed and we are so honored that she had come on with us, or, had us along with her on this new incantation of the House of Halliwell."

In Charmed , which ran from 1996 to 2006, Doherty and Holly Marie Combs starred opposite Alyssa Milano , who played the third Halliwell sister, Phoebe. Doherty appeared on the show until Season 3. (She was replaced by Rose McGowan's Paige in Season 4.)

Krause, meanwhile, who played Leo Wyatt, Combs' husband, on the WB series, revealed since announcing the relaunch and the news that Doherty would be joining the podcast, the Beverly Hills, 90210 alum had recorded four episodes of the rewatch podcast, all of which they still plan to release.

"We were lucky enough to record four episodes in the last week or so, and Shannen was just so motivated and determined to help make this show a success and give all of you more insight into what it was in the making and the fun and the behind-the-scenes of Charmed ," Krause said.

Touching on her work ethic, the 55-year-old actor added that if Doherty "wanted something done, she got it done, and that's something I learned a long time ago, watching her on set and work and be such a professional and so good at what she did."

The impression she made on him was a "lasting" and "lifelong" one, with Krause getting emotional before closing out the introduction to the podcast episode, which saw Krause, Combs, Doherty and Drew Fuller look back on the 1998 pilot episode of Charmed .

"So perhaps I'll leave you off with this: I know how grateful Shannen was, as I was lucky enough to travel with her to many different places and ComicCons and go backstage and hear from her the things that affected her emotionally," Krause said. "It gave her so much, emotionally, and meeting the fans and hearing the stories and knowing how much it meant to all of you, it filled her greatly and I know that she believed in the House of Halliwell to be the little bit that she was able to give back."

He maintained that the remaining trio will move forward with the rewatch podcast to "honor" Doherty.

"[We'll] continue on in her name, and kick freaking ass, because that's what she would do," he added. "So from us at the House of Halliwell -- we love you and we thank you and please keep Shannen in your prayers."
