Fox has released a first look for Lucifer Season 3. We see that Lucifer (Tom Ellis) has his wings back, which is in a way telling him he's an angel again. And, as you'd expect, you tell Lucifer he's an angel and he will go out of his way to act like a devil. So, we can expect a very naughty Lucifer when the new season begins.
We also get our first look at Marcus Pierce (Tom Welling), who seems to know just how to push everyone's buttons. He immediately refers to Chloe Decker (Lauren German) as Lucifer's partner instead of him being her consultant. He also picks up on the fact that Dan Espinoza (Kevin Alejandro) doesn't like Lucifer and asks him for everything he's gathered on the consultant. We've only seen a few seconds of his character, but already we see that he's a master manipulator. And if we hasn't already been assured that Marcus is human, I'd start to wonder.
There also seems to be some storyline coming up involving someone giving out favors, something Lucifer feels is his domain. The best line in the promo is at the end when Dr. Linda (Rachael Harris) tells Lucifer, "You didn't invent the idea of giving out favors." Then, after getting a look from him, "Yup… forgot who I was talking to."
Lucifer Season 3 premieres October 2nd on Fox.
