Long time fans of Blink remember when she first started her career as a pokemon coordinator and her team consisted not one but two sylveons: a regular one named Primrose and a shiny one named Doli.
The two were siblings and some of the first pokemon that Aika received when she started her journey and were her life-long partners until she finally started to make it big within the coordinating sphere. It was then that, after an unfortunate incident with an obsessive fan, Doli was physically scarred with one of her two ribbon feelers being amputated. Since then Doli has reclused to being more of a lap pokemon. Something that she didn't mind as she found it to be much more enjoyable than being an actor in the limelight or a battler like her brother.
She found joy in helping Blink during her creative process, acting as a sort of guiding light/second opinion when it came to designs for her clothing, lyric choices for her songs or what sort of effects she and her team should create during her performances. On the occasion, she'd help her with her day job as an assistant in a pokemon center but that was something that most of her team did, just to lighten her load a little.
Ever since the incident, she's much more guarded around other people and doesn't like to be touched unless given permission to do so (with the only exception being Blink but that's because they're her partners). Because of this, a lot of people who come across Doli always assumes she's just a priss/or has a very uptight-princessy attitude, when really she's just scared. Though, when it's just them at home, she's much more of a cuddle bug. Somewhat clingy and will absolutely use her powers to 'bully' Blink into spending time with her.
On the other hand, Primrose was the one that found it easier to pickup on routines, performances, and 'acting' for when their performances called for it. Essentially the type of pokemon you want to have as a partner for a coordinator. Though he prefers to be in the limelight, he (Blink not so much) is absolutely battle-ready and is ready to act if tried to underestimate him. He's acts very brotherly towards the team, trying to look out for them as much as he can but likes to do so from the sidelines rather than playing along with them.
To Blink, though, he's kinda like a service pokemon. He's likely the one to be out during her day to day life to help her navigate social situations if need be. He's very sociable too and often has his feelers on or around her to gauge how she's feeling at any given time. But because he does so much, he's kinda reclusive once they get home and is often lazing around, basking in the sunlight.
