Ferguson discussed the incident in his post on the SB Nation MMA blog:
Why did I bring up Charlie's son? I have no idea, but I have a guess. My birth father wasn't there for me growing up. Somehow Charlie's situation mixed in with my adrenaline from fighting and the booze all worked together to bring up my own issues. I learned a lot about myself watching that on tape and how I felt about certain things in my life. I was under a lot of pressure, I was trying to bottle up frustration and it didn't work. Well, it worked for a while, but ultimately did not.
I said some things I shouldn't have said. I was in a weird place. I was having crazy dreams in that house. The entire experience took me out of my own independence and removed all of my release valves.
I really regret saying what I said to Charlie and we've talked about it since the incident. I've spoke to Clay Harvison and Chuck, too. We are in a better place now than we were that night.
In the post, Ferguson mentions that they started drinking immediately after the fights, and adrenaline was still pumping through his veins.
Every TUF castmate I've spoken to has mentioned how weird the experience is. They're in a house for six weeks with no television, books, visitors or privacy. They get to train, drink, and entertain each other. This is not to excuse Ferguson's behavior, but just to point out that this isn't a normal situation, and abnormal behavior comes out of it.
