Summer will eventually come to an end and everyone will have to leave Palos Hills again, but there will be some big changes the gang will have to make before they all head their separate ways again on Awkward.

In a new trailer for the back half of what is supposed to be the show's final season, things will get more serious for Jenna (Ashley Rickards) as she and Luke (Evan Williams) continue their relationship, but the past with Matty (Beau Mirchoff) could still threaten to affect her love life again-and Matty may have a shocking question he wants to ask her before she heads back to Wyckoff.

"No matter how much more grown up I felt, I couldn't help repeating the mistakes of the past. It was time to make this right, no matter what," Jenna says in the trailer.

It appears that she and Matty will once again be on the outs, despite starting to rebuild a friendship, but that won't stop him from taking some action after she and Luke continue getting serious-and he potentially fears losing her forever, which makes him decide to take action while revisiting his past as a counselor at the camp where he and Jenna hooked up for the first time.

"Is it for you or a girl?" A kid asks him as he pulls out an arts and crafts ring.

"It's for a girl," he replies.

Meanwhile, something will also seem to set Sadie (Molly Tarlov) off that will cause her to suddenly decide she no longer wants anything to do with her old friends-but that moment where she decides to lay it all out there could prove to be her true undoing.

"Matty, Jake, Lissa and Tamara, I would literally rather die than be friends with you," she cries in a clip while driving the food truck.

Then, she is seen screaming as another truck heads for hers-and Tamara (Jillian Rose Reed) and Jenna are seen running into the hospital where they could encounter a very upset looking Sergio (Niko Pepaj).
