I know that they both competed in a swim in Hawaii July 7th...and they're still together. He supposedly has proposed to her, but I haven't heard anything about a wedding date. A friend of mine is Andy's best friend, Mitch aka, "Gatsby", who was on one of the episodes.
I'm happy for Ryan and Trista! They're a really darling couple; I went to their wedding...NOT, lol...well, I DID go up to where they had their wedding but could only drive past the hotel; they had too much security up there for anyone to get in other than invitees, go figure, haha. I just HAD to go check it out though
