But your theory deff has traction. He could easily have started to see the foundation for this lie start to crumble and went to college officials just to get a jump on the situation to make it seem like he was concerned he was being played for a fool before anyone called him out on it first. Pretty much saving face.
But like we all know lies and always found out. And covering up a lie with another lie with another lie at the end it always eventually breaks down and the truth comes out because after a while shit just doesnt make sense, or they say something that contradicts what they previously said, or they back track and say oh well i said that but i meant this.
In the end the truth comes out. It always does. I just hope for his sake he is telling the truth or he just screwed himself.
