Phil Coulson's team and the Rosalind Price-headed ATCU will work together to find the Inhuman Lash on "Devils You Know," the fourth episode of "Marvel's Agents of S.H.I.E.L.D." this season three.

Instead of racing against one another, the two leaders Coulson (Clark Gregg) and Price (Constance Zimmer of "UnReal" ) decided to stick with one another to increase their chance to contain Lash (Matthew Willig).

A trailer for Tuesday's episode of the series produced by Marvel Television and ABC Network is already uploaded on YouTube, showing their next common mission.

The synopsis for the "Devils You Know" episode is also featured on the clip's description, that reads:

"Having reluctantly agreed to share information with Rosalind and the ATCU, Coulson and the team go in search for the Inhuman who is killing off other Inhumans, and May feels that Hunter's mission to take down Ward is getting too personal."

It is important for the two groups to find Lash soon. Lash is a powered individual with a monstrous form but his "ability to absorb and expel energy," per Comic Book, is a lot scarier, especially with what he has been doing with his enhanced traits. In the premiere episode, Lash was already seen killing innocent people in the hospital where the Inhuman Lincoln (Luke Mitchell) was working. He is also linked with the various Inhumans found dead and killed by the same "energy weapon" recovered by Price's team seen on the first episode, titled "Laws of Nature", another article on Comic Book noted.

Why is he killing his fellow Inhumans? The next episode may reveal why he is doing such terrible acts.

Viewers may also expect more from him like what Elizabeth Henstridge, the actress portraying Jemma Simmons, has teased on Zap2It.

"He's going to shake things up. It's going to be a huge spectacle. We're so honored to be able to have him in the show. It's just huge. I can't even explain how crazy it's going to get," Henstridge shared.

Still, it may not be an easy road for Coulson to take, because Daisy Johnson (Chloe Bennet), an Inhuman too with earthquake-like abilities, is not so fine with his idea of teaming up with the ATCU, especially with Price thinking each Inhuman is a threat to society, per the clip below.

"Devils You Know," written by Paul Zbszewski and directed by Ron Underwood, will air on Oct. 20 (9:00-10:00 p.m., ET) on ABC, a separate article from Comic Book noted.
