Continuity mistake: Right after Carlos kills Alejandro with the candlestick, he throws the candlestick to the left of Alejandro's body. But a few seconds later the candlestick has suddenly moved to near Alejandro's head.
Continuity mistake: Season 1, episode 1 (Pilot): While Gaby and Carlos are arguing in their house, we can see a sofa and some other items in a semi-circular alcove with five tall windows on the far wall of the front room, and a painting near the stairs. A minute later, Carlos leaves and Gaby is alone with John, and the room has changed drastically. The alcove is now a flat wall with two windows and a fireplace. The sofa and some other things are missing and the painting moved to above the fireplace. This inconsistency exists because after the pilot was filmed, the set was redesigned and the part of John Rowland was recast. The scenes with John were reshot after the redesign took place, but the majority of this episode, including the first half of this scene (the argument), used the original footage. (00:17:30)
