Fans turned to Twitter, some asking immediately whether it's Jason while others were trying to figure out where they knew him from.
The 44-year-old actor appears in the show, telling new headmistress Hope dire news about Moordale.
On social media, one fan wrote: "I can't believe I didn't realise Mark from the school board is Jason from Gavin and Stacey!"
Another added: "Omg Jason from Gavin & Stacey on Sex Education, what happened on the fishing trip bro?"
Robert isn't the only person leaving fans shook after it emerged that Alistair Petrie, who plays Mr Groff, is related to some of the cast.
You may have noticed a set of twins popping up from time-to-time, including in Moordale's science lab or smirking in the background during that infamous toilet sequence on the school trip to France.
Well, they belong to Pertie - in that they're his IRL sons.
The two stars are Cal and Brodie Petrie, the 18-year-old sons of Alistair Petrie - who also has an older son called Connor Swindells... Just kidding, he's actually called Angus, and he was born in 2000.
One fan called Lorna noticed the connection, and posted a video on TikTok to share the revelation.
They said: "THE HOT TWINS IN SEX ED ARE MR GROFF'S KIDS IRL."
One person commented: "WAIT I THINK I KNOW WHO YOU'RE TALKING ABOUT."
Another said: "I IMMEDIATELY KNEW WHAT TWINS YOU MEANT."
