I've been reading a lot of speculation about Rulon being disqualified, along with speculation as to what he did, much of which is what's been mentioned here.
Possibly the reason isn't any one of these things, but ALL of them put together & being warned one too many times. I could see that happening.
Unlike many, I liked Rulon a lot & hoped he'd make it to the end, but it was becoming apparent that something was just off with him. He seemed to be there to lose weight & prove to himself that he could, but that's all. His competitive nature was all it seemed to be about for him.
He didn't seem to want to address why or how he had gained so much, or really want to change his behavior for the future.
It all seemed to have a just-here-and-now feel to it for him.
This show isn't just about weight loss, but about changing your behavior & lifestyle. He just didn't seem to get that part.
I'll be interested to see if he's there for the finale & if he's continued at all on his own. Also I'd like to see what he looks like in 6-12 months from then. Once the competition is over, will he quit & go back to his old habits?
