Te'o apparently did an
off-the-camera interview with ESPN, telling his side of the story. He claims Tuiasosopo has confessed to him. He also claims that he lied to his parents, and others about not ever having met Kekua, and that when he tried to Skype, the picture was always blocked. Additionally he says that the relationship was not continuous, but off again-on again, and that after his grandmother's death the girl reached out to him, and he didn't want to be bothered, so they fought, and then later was told she had died. He also claims that the Dec. 6th call was not actually a call with a confession, but a call trying to resume the relationship, which was very confusing to him.
The big question is, where is Tuiasosopo, and why hasn't he come forward to tell his version? Where is this alleged girl that made the calls? The second biggest unresolved question is, did Te'o provide his phone records to show all these purported conversations?
1. Manti was in on it, and did it for publicity
2. Manti was in on it, and did it to cover for being gay
3. Manti was the victim of a "catfish" scheme, and he and his family made a few "white lies" along the way, so that no one would ask how it was that he never actually met her in real life, and these are now coming back to haunt him
4. "Reba" was actually in on it. If Manti or his family thought they really met Kekua, they may have really met "Reba".
5. There really was a Lennay Kekua,
but she was an alien and she had blown her cover, so Will Smith had to deport her back to Venus. He forgot to neuralize Reagan Mauia, which is why he remembers meeting her.
The best explanation for Tuiasosopo's silence is probably #5, and that he, too, has returned to Venus. BTW, they may not have forgotten to use the neuralizer on Mauia - I'm pretty sure neuralizers don't work on fullbacks.
Sadly my take is that he's probably out trying to sign a movie contract before he speaks. As for the girl, where is she? If she exists, I would think she would want to speak up, and tell the truth.
