Sam (Jared Padalecki) and Dean Winchester (Jensen Ackles) will be back Thursday to hunt a werewolf as season 12 of the hit series "Supernatural" returns with episode 16.

The official trailer for the upcoming episode shows that Mick Davies (Adam Fergus) will follow Sam and Dean in their adventure. Mick is described by Claire Novak (Kathryn Love Newton) as a "totally lame" foreign exchange student.

There are speculations that Mick's presence will only slow the Winchester brothers down in their chase. One scene even shows him being in trouble, easily knocked down by an attacker.

The CW's "Supernatural" synopsis reads, "Sam and Dean search for a werewolf, and let Mick Davies tag along on the case. They soon run into Claire Novak, but their reunion is short lived after Claire is bitten and the brothers race to find a way to help her before she turns."

Meanwhile, the angels in heaven invite Castiel (Misha Collins) to unite with them as she has information on the woman carrying Lucifer's (Mark Pellegrino) baby, Kelly (Courtney Ford).

It can be recalled that episode 15 showed the return of Lucifer. Dean finally decided to work with the Men of Letters with a caveat that they are done once he feels that something is not right.

The Winchesters also partnered with Crowley (Mark Sheppard) in the previous episode in a hellhound battle. This episode reminded its viewers that Crowley is very powerful. Just when Lucifer thought that he is superior to Crowley, he was seen gasping in pain at the snap of the latter's fingers.

Crowley said he was just "getting started." It was, then, shown how he snapped Lucifer's bones with the most appropriate line, "I own you," Crowley powerfully said.

"Supernatural" season 12 episode 16 titled "Ladies Drink Free" will air Thursday, March 30, at 8 p.m. EDT on The CW.
