But Jeff’s puberty joke wasn’t the only moment from the March 26 episode that had everyone on social media talking.

Later, during the immunity challenge, Jeff broke down in tears for the first time in 48 seasons after contestant Eva Erickson shared her autism diagnosis with the entire cast after overcoming an extremely difficult puzzle.

“I was diagnosed when I was very, very young. Doctors told my parents I would never live independently, that I would never hold a job, that at most I could marry someone else with autism,” Eva told her fellow hopefuls. “They put me through so many different treatments to help me get all the support that I need, and I was able to then enter school and be mainstream. So, I’ve never viewed my autism as a roadblock to success.” 

Despite experiencing overstimulation during the challenge, Eva conquered the hurdle, prompting Jeff to praise her for “knowing something like this might happen, and then be brave enough to share your story” to other viewers with autism. 

“I’m a parent, and I do see it,” Jeff—who coparents wife Lisa Ann Russell‘s kids Michael, 21, and Ava, 18, with her ex Mark-Paul Gosselaar and his second wife Catriona McGinn—added, choking back tears. “Wow, this has never happened.”
