The only storyline that I remember that featured Rebecca was after the office was bombed and her mother showed up at the hospital and refused to allow her to receive a transfussion. Bobby was upset because he said all these years he never knew that Rebecca was Jehovah's Witness and her mother said "well how well do you know her?". It turned into a court case, Bobby lost, Rebecca almost died but she pulled through...they never addressed it again.
Wasted storyline, if your co-worker was a strict anything you would know it - even if you don't discuss it on a daily basis.
But then again - she went to law school at night for years and didn't tell anyone. Hell, she may bust up in there with a white boyfriend she forgot to mention
