"Yesterday I completely f---ed up," he admits. "I understand that your trust is something I might not be able to have now, but I want to be able to gain that trust back."

On last week's episode, Lindsay learned that DeMario had a girlfriend when he agreed to be on the show and told him to leave. However, in the clip, she seems open to the possibility of letting him re-join the show.

"As much as what he did hurt me," she says, "I think it took guts coming to the mansion tonight."
