One Life to Live Soap - Jess, Bess & Tess? I'm confused?

Bess is the one who wears gles and she comes out when Jessica doesn't know how to handle a situation. She first emerged when Jessica had her stillborn baby and she was behind taking Starr's baby Hope and leaving Chloe there. Bess also steps in if Tess is out of control and takes things too far. Tess comes out when Jessica has had something very traumatic happen to her, like when Nash died Tess reappeared.
