One contestant on last night's episode of Jeopardy said what everyone in the room was thinking, and it brought beloved host Alex Trebek to tears. 

During the show's “Final Jeopardy” round, “Tournament of Champions” contestant Dhruv Gaur gave up his shot at winning and instead bet $1,995 of his $2,000 on a message of support for Trebek in his fight against pancreatic cancer.

"What is we [love] you Alex," the message said.

The episode was filmed back in September, when Trebek announced he'd be receiving another round of treatment for his Stage 4 pancreatic cancer. 

Trebek was visibly touched by Gaur's message, as he thanked him and tried to choke back tears. 

Gaur took to Twitter last night to explain why he did what he did.

"Sorry for west coast spoilers, but I’m really glad I got the opportunity to say to Alex what everybody at the tournament was thinking," he tweeted.

"For context, Alex had just shared with us that he was reentering treatment for pancreatic cancer. We were all hurting for him so badly. When Final Jeopardy came up, I could’ve tried to puzzle it together, but really, just kept thinking about Alex, and thought he should know."

The final tweet in Gaur's thread contained the hashtag #weloveyoualex, and it quickly began trending on Twitter. 

I’m just very grateful I got the opportunity to say what I know everyone was thinking. Sending all the love. #weloveyoualex

People from all over began sharing their love and support for the Canadian icon. 

#WeLoveYouAlex I have grown up being taught great trivia, science, human culture and class by watching your show. Thank you kind Sir!

And many Thanked Gaur for saying what everyone else was already thinking.

But Gaur didn't just support Trebek with his words on last night's episode. He and his fellow contestants also sported purple ribbons in support of Pancreatic Cancer Awareness Month. 

And later, the thoughtful contestant posted on Twitter about how he and other “Tournament of Champions” contestants are encouraging viewers to donate to the Lustgarten Foundation for Pancreatic Cancer Research in honour of Trebek, as well as 2018 Teacher’s Tournament winner Larry Martin, who recently passed away of the same disease.

"With all the attention coming my way, I want to also re-up this play-along for Pancreatic Cancer on Thursday and Friday," Gaur said.

"Many of us are donating $1 for every question we get right when playing along at home to the Lustgarten Foundation for Pancreatic Cancer Research. Join along!"
