1. Brianna. Unlike basically everyone else, it seems like she was intended to become a Jedi. However, if I were actually the Exile, I wouldn't train her. She focuses too much on combat. Also, I bet that in about fifty years, being a Jedi historian and all, she's going to become Traya part three.
2. Mira. Again, not someone I'd actually train. She is a very moral person, but that doesn't make a Jedi. She has a lot of anger in her, and the a77it00d does not befit a Jedi.
3. Atton. I wouldn't actually train him either. In fact, I wouldn't actually train anyone except Mical. Atton is good at controlling his feelings, but I don't know if he's responsible enough to be a Jedi.
4. Mical. He would be first, but unfortunately for him I hate him. He has Jedi training (to an extent), and he's very peaceful and calm anyway.
5. Bao-Dur. He doesn't seem like a Force-sensitive, even if he is. If the Exile is a wound in the Force, Bao-Dur is a timebomb in the Force. Sure, he seems all nice now, but the instant someone mentions Mandalorians, he's probably gonna go off, get his face tattooed and get all Darth Maul.
