This is just in case anyone else had the same nagging feeling, but Sunny from ep. 2 has been on another reality show previously.
She seemed vaguely familiar so I did a little googling and realized that what I remembered her from was Virtually In Love that was on Oxygen last year. She was in the 7th episode with a guy she had been seeing online (Jake), not the same guy who was her ex on this show (Matt).
And now I am off to see if there is a support group for people who watch too much crap reality tv.
