ya, he had to have known because
1. his friend is the one that made up the account
2. what type of idiot says "it was nice meeting you", and a school article saying "Their stares got pleasantly tangled, then Manti Te'o extended his hand to the stranger with a warm smile and soulful eyes. Kekua, a Stanford student, swaps phone numbers with Te'o." to a fake person that they never met.
3. what high profile person is in a relationship for over half a year without seeing her and is perfectly fine with it?
4. why cant manti correct his father when he said "Every once in a while, she would travel to Hawaii, and that happened to be the time Manti was home, so he would meet with her there." There was no meeting, she is fake.
5. "i miss you"... you cant miss someone you never met.
