|Portrayed by||Markie Post|
Leslie changed her name when she became a nun, and was called Sister Theresa. She didn't want Face back in her life; she just wanted to tie up loose ends because she thought that she was about to die. Even though she chose to become a nun instead of marrying him, she still prayed for Face every night.
