It was smooth sailing for America's Next Top Model's first runner up, Chantal, until she ran into a huge challenge on the runway last night that may have been the reason she was sent home.

"Walking on that runway next to Saleisha was the most challenging [moment]. She's so good and that got to me. We were so close to the end and any little thing could make you or break you."

Say like tripping over a guy on stilts with your dress?

"As soon as that happened. I was like 'Oh my God, you've got to be kidding. This cannot be happening,'" Chantal said. While she was concerned about the man that fell, she learned that her first priority should have been the runway.

"I definitely reacted. That's what you're not supposed to do. You're supposed to stay in character…I saw him fall and I lost it. I should have kept on walking—no reaction. I learned from that."
