Shannen Dohertyhad a very special reason for signing on to the reboot ofBeverly Hills, 90210.

On Wednesday, Doherty, 48, said duringBH90210‘s panel at the Television Critics Association press tour in Beverly Hills that she didn’t initially plan to join the reboot, despite a majority of the original cast signing on.

“For me, as these guys know, I definitely wasn’t going to do it,” the actress told the audience. “Nothing against the show, I knew it would get sold and do well without me. They didn’t need me. At that moment it wasn’t what I wanted to be doing.”

Things changed, however, when her former costarLuke Perrytragicallydied in Marchat age 52 after suffering a massive stroke.

“When Luke passed away, things drastically changed for me and I felt like it was a great opportunity to honor him,” she explained. “And I’m really glad I made that decision because now I get to sit up here with a lot of people that I respect and love.”

“We went on this amazing journey together where we also got to really, sort of, heal through losing somebody who means the world to all of us,” Doherty added.

Luke reached out to me during my cancer journey and we picked right back up, albeit older and wiser, but that connection remained intact,” said Doherty, who opened up about beingin remissionin September.
