If Your influence is strong enough he will trust you and you will train him. Disciple will then become a Jedi Counsular.

Revive Dead Party Members
If one or both of your teammates is killed in a battle, get your own character to a safe distance out of battle and have them use an item that does not bring anything up on the screen. For example: a speeder that is lying out in the open, or a door that won't open. After you use it your partner(s) will stand up and continue attacking. However, when they get back up their health will be extremely low.

Bao-Dur Uses the Force
