Raelynn Babblos by @Solangelo2KOTLC (She writes awesome PJO fics go check her out :D)

Pink

Shade, Psionpath

Jensi's big sister got Exiled when she almost killed brother. She was ten and she had just manifested, when she accidentally sent Shadow Flux at him. They were able to find a shade and Jensi was back to normal, but Raelynn was upset. She was Exiled and her parents didn't do anything to stop it. They were mad at her for hurting 'their little baby'. At Exile, she manifested again as a Psionpath. She is able to put shadows on the walls of her force fields, making them nearly impenetrable .

Almost killing her brother

Brown hair with pink highlights. Short; If you compare her to anybody her age, she looks younger than then. She is the same hight as Jensi. 

17 

She has a lot of anxiety. 

Follower, Unsure, Naive 

 Jensi forgave her when her family didn't. She doesn't cuss but she also doesn't mind if others do. She goes by the name Pink because she always is wearing something pink.

Jensi, Fernan
