must have been orange "good" then yeah
The "Good!" bubble will appear when you press Up on your Dpad. If your partner had done something significant, they will acknowledge that your so-called praise, raising affection and also imprinting in their AI: Main character just praised me on this move, I might use it more frequently next time.
So basically, through praising etc, it might be possible for you to adjust their skills etc so that they will only do the required actions that you IMPRINTED them to do.
You can adjust such settings via talking to the partners and setting up the way they fight:
mainly: ATTACKING/DEFENSIVE/SUPPORTIVE
Whenever they do an action, you might see a "Att Skill" icon thing appearing around bottom left corner of your screen. If you are going for the Attack build to unlock their Attack armour, only praise moves that are of the "Att Skill" variety, such as certain sword skills/joining you with a joint attack etc.
Reason being, if you praise them for every little thing just for that +50SP gain, your partner will more likely use a variety of skills, which makes it harder to condition them into unlocking specific Att/Def/Buff (Supportive) costumes that you can make them wear.
For example for joint attacks, there are two types. One, look out for "Kirito, use sword skill!" If you use a sword skill of any kind, most likely they might follow up with a Att Skill-based sword skill. There's also the "Kirito, let's use Sword Skills together!" message. When your partner is at rest (e.g not using any other active sword skill/supporting skill/have more than 100SP), using a sword skill will trigger the dual cut-ins of both you and your partner, and that joint attack is considered of the "Att Skill" type as well.
Lots of experimenting that you guys can do.
