Paula Reyes is a villainess from Elementary, appearing in Season One's "Details. She was played by Paula Garcés.
Paula Reyes is a police officer who was previously in a romantic relationship with Detective Marcus Bell, until she learned that Bell was the one who informed Internal Affairs about her corrupt superior. The superior was her top supporter regarding a promotion, most likely because she helped him plant evidence to get Bradshaw, a local drug dealer off the streets.
Paula turned heel and sought revenge on Bell, beginning with shooting and killing Bradshaw. After that, Paula shot Bell's brother, Andre, and tried to frame Bell for the crimes. Paula is eventually caught and arrested, but not before she delivers one final parting shot to Marcus. During her interrogation, the evil Paula stated that she's not surprised that Marcus wasn't there during the summation because saying things to her face "wasn't his style."
