Episode 14 • My Brother's Keeper
All out of Love (feat. Fallon)
Pierce joins Amenadiel at Lux, introduces himself, describes the hell he's been living, then accuses Amenadiel of marking him at their father's command.
Lucifer returns to Lux to find it trashed, then Amenadiel admits to him that her was the one that marked Pierce; Lucifer informs Amenadiel he doesn't need his protection, then warns him against continuing to meddle in his life.
C'mon, there's no such thing as a stupid question. Get the ball rolling and be the first.
