In The Ones You Love, Artie, while split into Good and Evil Artie, kills Leena, a WOC and series regular who, though having been around for 3.5 seasons, has yet to receive a last name or any other characterization beyond "B&B owner" and "tool of McPherson."
Two episodes later, in The Living and the Dead, despite the existence of multiple artifacts that can bring people back to life, Leena is still dead. However, no one gives a shit, except insofar as her death causes angst to a white man [Artie]. In fact, she appears in Artie’s subconscious as an essentially vacuous prop to demonstrate the painful reality from which he’s shielding himself. Claudia and Steve exercise themselves mightily over drawing Artie out from his subconscious, paying no attention to Leena except as a tragic figment of his imagination. Who cares about the black woman?
In the next episode, Parks and Rehabilitation, Artie stands on tribunal in front of the Regents, who decide to reinstate him as head of Warehouse 13 because
Saul Rubinek has an ongoing contract with the SyFy network the plot must go on. The head Regent explains that Artie was kind of possessed by an evil version of himself, so he’s morally blameless. He also says that "Leena was a valued member of the team" and that "she knew the risks."
I buy neither statement. First, Evil Artie was in fact Artie, just a concentrated version of those thoughts and feelings that he censors in his attempt to be a good, kind person. As a part of Artie, Evil Artie is indeed under Artie’s jurisdiction and part of his responsibility. No matter what the show wants me to believe, Artie willingly, knowingly and with malice aforethought murdered Leena.
Second, if Leena was such a "valued member of the team," why the hell do we never see her doing anything but being victimized and keeping house in the background? And why the hell couldn’t the Regents refer to her by her full name?
Oh right, it’s because she’s a cardboard Mammy. :[
