While Lucas kept the details sparse (he won't reveal his fiancee's name) he did say that an encounter with a mountain lion while staying at an "eco retreat" was what made him realize she was "the one."

"I hear, totally serious, two big breaths, and six feet above me, I see the very slight glint of the eyes of a huge [mountain lion] and I literally proceed to do what I had just read in the instructions," he explained. "And I started screaming and yelling and literally being as crazy as I could be, it padded off and just slowly went away and I worked my way into the trailer and I got in and I decided at that moment that this woman was the woman for me."
