I didn't really understand if you want us to, so here, I'm giving you their personality.
Mystery:
She never lets anything slip from her eye. She's very focused and sometimes uptight, and she is always looking for a new mystery to investigate, and she puts her nose where she shouldn't. She's often risking herself, yet that's what she loves to do. She is also paranoid, and she suspects everyone in her eyesight.
Flyaway:
She hates being in the same place for too long. She's traveling a lot, leaving dust behind her. She is pretty fast, and corious. She's creative and fun, and she is always looking after her sister, Mystery, altough Mystery hurts her. She might be presenting love and peace, but inside, she just wants to escape, somewhere she can erase all of her memory.
