It's not even halfway through the season, and the Survivor castaways are already feeling the stress of the competition.

Only ET has an exclusive first look at Wednesday's episode of Survivor: Game Changers, where one castaway in particular can't help but shed a few tears -- even after orchestrating some of the most brutal moves of the season so far.

"You don't realize what you go through. It's amazing. You know, I've played the game. I've played for 12 days, I didn't know how hard it was on [my wife] Monica to get this far," a teary-eyed Brad Culpepper shares with his tribemates, Aubry, Sierra, Cirie and Troyzan, while Aubry bursts into tears.

"She got hungry. She's different. She was hurt. I don't know that I understood why she was hurt," Culpepper continues, wiping away his tears. "And it's only been 17 days and I can't... that's enough for me."

Culpepper later walks off to clear his head, but it's obvious that Monica's still on his mind.

"When Monica and I played Blood vs. Water, she got all the way to Day 39, and I don't know that I truly appreciated it until I had been here 17 days," he tells the camera. "For her to do what she did, she's a tough cookie, and has kind of been a guide for me. She's been my strength and my compass, right on my arm."
