Myers-Briggs: IFSJ-T
Reva is quiet, quieter than most of her kind, even. She's not likely to approach people. The exception would be if she feels someone needs her medical assistance, which is where the Konti knows how to take charge and give orders. She is also very levelheaded in fast-paced medical situations, when she needs to focus on giving the patient what they need.
Reva also adores children, and is almost maternal in her behavior towards them. This is another situation in which she opts to come out of her shell, playing and laughing with younger generations. She will take on a maternal role when comforting or advising peers, though some may perceive it as patronizing or condescending.
When Reva finds a friend or lover she connects to, she may not be as good of an emotional empathizer as other Konti with more feeling-honed gifts, but she will listen, and she will care as best she can. She's also very careful about others getting physically hurt, and will encourage them to take precautions.
Generally, Reva is careful and cautious, and doesn't take drastic action unless she considers it first. It is rare that Reva will just do something "on a whim," and she's not impulsive in the slightest, which can often cause her to miss out on fun opportunities. However, in the right scenarios, because she isn't likely to outright say no, Reva can succumb to peer pressure and do things she normally wouldn't.
Note to selfA thread where someone gets her to come out of her shell could be fun!
