Try to figure out who or what you are.

Was she still Rebekah? It didn't feel that way...but at the same time it did. As she focused on figuring out who she was primarily, it became clear that the necklace did this somehow. Trying to focus on her Rebekah parts she suddenly realized this was true...

However it didn't stop there, the fusion girl then had access to Rebekah's thought process and knowledge. Trying to sort the memories of family was somewhat difficult because they conflicted with the other girls' memories. She thought if she focused on the things she was taught throughout life academically and perhaps through muscle memory, those would come back easily.

The necklace would glow as somehow, all of her parts worked together on this. This caused her to get down on the sand, lay back, take in the sun and moan through her lips a little as she felt around her nether regions while her fingers rubbed against the fabric. Her body was calibrating it's capabilities in a rush of experience and it felt...oddly exhilarating.

"Mmmmnnn..." she sounded out, as if taking on some high. Due to the fact her knowledge skills increased, she surmised it might actually be a high...

Wait, that is actually a great assumption on her part. Rebekah is smart but limited to basic college courses and a few extracurricular ones. She didn't know psychiatry or knowledge of mental processes. Holy shit, she thought, one of the girls is really smart. In particular it had to be the one who did indoor swimming, Amber, which actually was true. Despite the realization, the fusion woman suddenly gained a window into Amber's life. Amber Feinlin was a rich girl carrying the honor of her family name on her back. She recently got tired of the constant pursuit into medical and biological sciences while at her college. She wanted some time for herself. She decided to take up swimming and bunk with Chelsea, who the fusion woman could now see was the other part of her opening up. Chelsea was indeed professional at swimming, so much in fact she could pass as a lifeguard here. They were highschool friends that swam together on regularly, with some of Chelsea's training rubbing off on Amber.

It was at this point the fusion laid further back and her hands were flat against the sand, as she went into a trance marked by her green glowing eyes.
