"Stranger Things" season three trailer two Billy Dacre Montgomery

The creators of Stranger Things are keeping fans guessing in the second preview for the upcoming season. 

Unexpectedly, leading this latest update is the nefarious antagonist Billy (Dacre Montgomery). The absurdly handsome villain was first seen in the second season of the show as Max's (Sadie Sink) violent older stepbrother. 

The first trailer gave fans an idea of what to expect in the summer season. The third installment of the Netflix series portrays the kids growing up and living a preteen nostalgic-for-the-'80s existence, plus a new (even scarier) monster. And this teaser appears to be a drool-worthy look at the past season's bad guy.

Take a look at the second trailer for the upcoming season. 

In the first season, Billy is portrayed as a violent bully with a tumultuous home life. He harasses his stepsister, Max, Joe Keery's character Steve Harrington, and the rest of their young friends. 

In this trailer, Billy is the Hawkins' lifeguard, getting lots of attention from the teenage girls and adult women in town. In one scene, he growls at a young boy to stop running, but it's difficult to say if he's still the bully that he was throughout season two. 

Billy was introduced as a notorious bully in the second season, but is that what's planned for the season ahead?

At the end of season two, Max took on her menacing older stepbrother as he beat Steve Harrington to a pulp. She stabbed him with a tranquilizer syringe and threatened him with a baseball bat to leave her alone. The last we saw Billy, he had agreed to leave the gang alone, but it's difficult to say if he's left behind his bullying ways altogether in the third season. 

This promotional image is captioned, "One Billy can change everything." It's possible the caption is insinuating that Billy will help the kids with the true Hawkins villain in the third season, or it could also mean the opposite. 

In the second season, Billy was a hit among the mothers of Hawkins. Nothing's changed in that department it seems.

In one scene in season two, Billy flirts with Mrs. Wheeler (Cara Buono), Mike's (Finn Wolfhard) mother. This trailer suggests that the inappropriate relationship between the two is explored further. When Billy enters the neighborhood pool, shirtless, to take his post as lifeguard, the moms in Hawkins definitely take notice. 

Dacre Montgomery's campaign in H&M's collection collab with Stranger Things clearly foreshadowed more about the third season than originally thought.

The summer line, which will be released on May 23, features plenty of pool gear, bathing suits, hats, fanny packs, and T-shirts based on the show's iconic logo. Montgomery posed in character for the editorial shoot promoting the new collection. The first trailer for the upcoming season showed a scene in which Montgomery starred as the town lifeguard, but after seeing this second preview, it's clear that plays a larger role in the show. 

If you haven't seen the first trailer for the third season, prepare for chills. 

The Who's "Teenage Wasteland" plays as the significantly aged gang of friends rides bikes (of course) and explores the town mall and the outskirts of Hawkins.

Finn Wolfhard's character, Mike, makes a comment about the friends growing up: "We're not kids anymore. I mean, what did you think, we were just going to sit in my basement all day and play games for the rest of our lives?"

Mike and Eleven are deep in their young love summer romance, as seen in this hand-holding shot.

One shot from the trailer shows the young teens trekking up a hill together, and if you look really close, you can see Mike and Eleven holding hands. The last we saw, the two shared their second kiss at the school dance. Now they're experiencing their first relationship and a summer romance. Another still shows the two kissing among the chaos that is bound to ensue. 

If I didn't already stan this duo's friendship, I definitely do now.

Eleven (Millie Bobby Brown) has come a long way since her days in the lab as a test subject. She has a boyfriend, and her friendship with Max is blooming. This duo explore the mall together, dance to music, and start to dress up in the trailer. 

This photo shared by the show's Instagram account is captioned, "Introducing your July 4th dress code." A second promotional photo for the upcoming season states, "One friendship can change everything."

This suspicious gaze from Mrs. Wheeler is ultra concerning.

One still during a flash of clips in the trailer shows Mike's mom giving Billy a telling look at the pool. Their relationship already got an inappropriate start in the second season, and this gaze is super worrisome for the Hawkins mother. Billy flirted shamelessly in the second season, and in the second trailer it's clear all of the moms have eyes for the high schooler (ick). 

The new monster is quite possibly the most grotesque.

The monsters in Stranger Things are always frightening. This new, creepy shot from the trailer shows that the upcoming creature looks similar to the monsters we've seen before. But extra limbs, a grotesque roar, and a mouth full of razor-sharp teeth prove it might be the scariest version of the beast so far. 

The promotion for the upcoming series is getting fans so hype for the season. 

July 4 can't get here soon enough. This final promotional shot of our favorite trio of awkward preteen besties is captioned, "OUR BOYS CAN CHANGE EVERYTHING." Something is definitely "changing" in Hawkins this season, and fans cannot wait to find out how.
