During the 90s Con panel, the four actors also paid tribute to their late co-star, Shannen Doherty. The group publicly reunited just two months after Doherty died on July 13, nearly a decade after she was diagnosed with cancer. She was 53.

Green recalled his longtime friend’s “incredibly brave” and “difficult” cancer journey. “She’s a great example to me for everyone of (how) she put her own challenges and her own health aside and really wanted to share the experience of everything with everyone, and it was incredibly brave,” he said. “To go through something so difficult and be open with complete transparency and share it with everyone is brave.”

Carteris noted how the actress became an inspiration to people in her own life. “I have a friend now who is very sick with cancer, and she said Shannen really inspired her,” she said. “I think her legacy really makes a difference for those who are struggling to know that there is hope.”
