He comes into the free skate portion of the event leading the field after his record-breaking performance in the short program two nights ago.
Chen's coach, Rafael Arutyunyan, has helped guide some of the biggest stars the sport of figure skating has seen in modern times - from Michelle Kwan to Sasha Cohen to Adam Rippon to Ashley Wagner.
But he's never had a pupil like Chen, and certainly never had a pupil undergo the kind of journey Chen has taken.

Chen's comeback from a disappointing 17th-place finish in the short program in Pyeongchang in 2018 and ultimately missing out on a medal, to winning gold at the next three World Championships and going on an incredible run of dominance that has him on the precipice of winning gold in Beijing, is unlike anything Arutyunyan has seen before.
According to the Associated Press, after the disappointment in South Korea, Chen "doubled down, working tirelessly" with Arutyunyan
"He sharpened every aspect of his figure skating, from technical marks to his artistry, and he began to put together programs that nobody else had the nerve to try," the AP recounted after Chen's historic short program success.
According to the official Olympics website, the "gruff Armenian who is famous for his poker face" Arutyunyan was on the verge of tears after Chen's performance.
"I was standing there and basically I didn't even move," he said. "I was watching, just a little bit I had tears in my eyes; it's emotional. That's because it was a long journey. I'm with him... I think it's more than 10 years already I'm working with him. And that's why I think I was emotional."
If Chen does indeed capture gold, it will have been the first time Arutyunyan has coached a skater to individual Olympic gold glory.
