Whats Going on MTV Challlenge "Where Are They Now

This will be my first male cast member of the "Where are They Now" segment which I'm looking forward to. This cast member  was a replacement cast member all the way back on Season 20 of Real World Hollywood. He ended up going  onto two consective challenges The Duel 2 as well as The Ruins. I'm talking about @NickBrownOnline. What has he been up to since the challenge? Why aren't any of his cast mates on challenges as of late.  Who does keep in contact with from the challenges and will he plan on coming back anytime soon
