Scott cycles up on 115 through two lines of traffic to meet up with Kira while it's pouring. Eventually, he catches sight of her. She's excitedly running up to him. Scott asks his girlfriend did she have fun in New York. Kira, beaming, replies "Not really." Relieved, Scott replies "Good". The two then share a deep kiss in the downpour.
Scott and Kira make it to the high school in time for the big event. They make out under the underpass. Suddenly, Scott hears a growl. The two are then attacked by a huge werewolf-like creature. Scott and Kira, whipping out a new sword, fight back. The creature thrashes them, and taunts Scott. Scott fully shifts and roars at the creature who he is. The werewolf-creature tells him he's come for the famous Scott McCall who took down Deucalion and broke the Argents' family. He raises his enormous glowing-blue claws and engages Scott again. Scott, knocked down, is almost gutted by the creature. A new werewolf arrives, and slashes the creature before he can stab Scott. Scott takes up the fight again, but is stabbed deep by the creature's claws. Scott's alpha red eyes dim as the claws seem to absorb or siphon his power. Stiles, Malia and Liam appear beside Kira and the stranger, on the scene looking grim. Scott manages to regain his power. He musters enough strength to overcome the claws - he breaks the monster's arm, leaving the monster in pain. Scott regains his footing, ripping the separated claws from his chest. He gives the monster a choice: leave or stay and Scott will break something else. The beaten creature chooses the former.
The pack turns to curiously face the stranger. The young man says that Scott doesn't remember him. He says it has been a long time since the fourth grade. Scott recognizes the new wolf: "Theo?" he asks. Theo nods. He tells everyone know he went to grade school with Scott and Stiles. Theo tells Scott he'd heard of him becoming not just an alpha, but a True Alpha. Theo says he's come back to Beacon Hills because he wishes to be part of Scott's Pack.
Scott, along with Stiles, Kira and Malia, enter the school. Stiles is conversing that the two of them haven't seen Theo for years and he just suddenly shows up. Scott answers that he's more concerned about the creature that was just out for his blood. They meet up with Lydia. The five of them then head for the school library. All five are going to be seniors, excited to hae reached this particular milestone. They join the rest of the upcoming senior class for the big event: the Senior Scribe. In the library, they all write down their initials on a cleared book shelf to signify becoming seniors as a school rite of passage. Scott adds his initials last. A sad expression comes over his face as he comes to a decision. He adds Allison's initials next to his. The pack remember their fallen comrade. Lydia declares Allison is still with them. Scott leads the other four down the stairs, to begin senior year.
