I agree so much with Qui-Gon being what Ani needed when it came to the Jedi Order. He would have been a calming and understanding presence that Ani needed so much and of course, being the father that Ani lacked. Not to take anything away from Obi-Wan, because he tried, but perhaps he wasn't the best one to train Ani. Yes, he did care for him and viewed him as a brother, but as you said, Ani needed a father (and his mother, of course!).
