More than two decades later, it seems that the show still hadn’t left her mind, as she described it as a project that was “way ahead of its time” and shouted out its “badass guest stars.”

“I still have that compass necklace. #funfact,” she said on Instagram.

There, she formed close bonds, including with her on-screen sibling, with whom she celebrated her sweet 16th birthday.

She wrote on social media, “I am brave enough now as a 35-year-old woman… To repost this. Because. This must. Be known. As a teenager. With his not appropriate behavior… very. Not. Appropriate. So now. People know. What. Joss. Did.”
