Episode 8 of Lucifer, “Et Tu, Doctor?,” opens with a rather chipper Lucifer in the midst of celebrating his “re-birthday party.” The fallen angel feels reborn now that he has scorched his wings and bade farewell for good to his old life. Lucifer is now free to be, in his words, “Whoever the Hell I want to be.”
The Morningstar makes his return to Dr. Linda Martin, Lucifer apologetic about their last session ending with his violent explosion. Linda reassures Lucifer that, despite the damage done to her office, their last session was positive because they made a real breakthrough, as Lucifer let down his barriers—barriers which, Lucifer makes clear, he would prefer to have back up. Linda observes that he appears to be jealous (envious would be more appropriate) of Chloe’s ex, Dan—“detective douche,” as Lucifer repeatedly refers to him. “The Devil doesn’t get jealous,” Lucifer retorts. “I’m the one who inspires passion in others.” While Lucifer wants Linda to look into Chloe—who, for failing to throw herself at the Devil’s feet like all other women, is in his eyes obviously not right in the head—the episode revolves around Lucifer’s self-examination to discover whether or not he is indeed green with envy. (Lucifer is sure to play up the love triangle element, as “Et Tu, Doctor?” both has Chloe lock lips with Dan and reveals that Dan was the mysterious gunman in the Palmetto shooting, which left Chloe an outcast in her department and has continued to haunt her career ever since.)
At the end of the episode, as Lucifer is prepared to make up for late carnal payments to his therapist, Linda explains that, going forward, it would be best for them to keep their relationship strictly professional. It is not exactly clear why this is. Perhaps because Linda met Mazikeen, who informed her that sleeping with Lucifer was destined to end with her being discarded like trash. Or perhaps because Linda met Chloe and sees potential for Lucifer’s progress in his longing for a relationship of sorts with the enigmatic officer. Curiously, Lucifer is not piqued by Linda’s termination of their sexual relationship. He is, however, incensed when he figures out the true identity of the biblically named Dr. Canaan in the office next door, Lucifer realizing that Linda has had “an angel on her shoulder trying to control me.”
Lucifer confronts Mazikeen, who is guilty of pointing Amenadiel in Linda’s direction, observing that her self-serving betrayal is indicative of the human world rubbing off on her rather than him. With that, Lucifer breaks with his long-time partner and friend. It will be interesting to see how this develops (Lucifer and Mazikeen do split for a time in the Lucifer comic); surely Mazikeen’s possession of one of Lucifer’s feathers will play a part in the proceedings.
