Mercedes Walters, also known as the girl no one has ever heard of. She is a bit paranoid and seems to constantly forget her own name. But the truth is Mercedes had witnessed a gruesome murder and needed to be safe. So witness protection relocated her, changed her name, and stuck her with a bunch of privileged kids, and gave her a chance to have everything she never had… money, a name for herself, a “family” pretty much a chance to be any one she wants too be. Mercedes often tries not to get too close in fear that she will be found and forced to leave Easton on a whim.
