Season 4 episode 1: Scott and his friends are all in Mexico right now trying to find Derek.
Becca's plane landed at 9:00 on Saturday night. When she was leaving baggage claim she looked up and saw her cousin still clad in his deputy uniform. She ran as fast as she could to him while lugging her huge bag behind her. She jumped into his open arms.
"I missed you so much." He whispered into her hair.
"I missed you, too."
They released each other and Parrish grabbed her bag to take to his car. They drove to his apartment, talking the whole way, catching up. Neither of them spoke about why she was coming to live with him, it could wait until tomorrow. When they walked in Parrish brought her to her room and she immediately flopped across her bed to sleep. She was still on New Jersey time, which was 6:00, travelling was draining and she was exhausted. Parish turned off her light and went to his room to do the same. He was also exhausted from a day of working at the station, plus he had an early shift tomorrow morning.
About thirty minutes later Becca sat up in bed. She smelt something drifting through the air. She had never smelt it before but it seemed familiar at the same time. She felt a pull to leave the apartment so she quickly put on a sweatshirt over the comfy clothes she wore on the plane that she never took off before sleeping. She slipped out the door and into the street. She paused for a moment. What now? What am I even doing out here? She thought, but then found herself walking down the street towards the woods. She walked through the dark woods, scraping her legs on branches and bushes, but she ignored the dirt and scratches. All she could think about was finding the source of the scent.
After a few minutes she reached the other side of the woods and ended up on a street. Suddenly, she was at the end of the driveway of a house she had never seen before but the scent was emanating from it. On the mailbox, in white lettering, was the name McCall.
"Scott," she breathed. Then, Becca grew more confused. Scott McCall. She had never heard that name before.
She went up the walkway and knocked on the door, a woman with curly brown hair opened it.
"Can I help you?" the woman asked.
"Gosh, this probably sounds crazy, but I just moved here and I felt, like, drawn to this house, something about the scent I have no idea why, but now that I said that I realize you probaably think I'm insane," Becca rambled.
Realizing this must be something supernatural, the woman spoke up "No, it's not crazy, it's probably my son, his name is-"
"Scott," Becca cut her off.
"Yes," the woman said confused. "I'm Melissa McCall. I think I know someone who can help you. Are you okay with that?"
Becca nodded. Melissa drove her to Deatons. On the car ride there, Becca saw her reflection. Little bits of sticks were tangled into her hair and dirt was streaked across her face and body. Then, she looked down at her legs and saw scrapes and cuts all over. Yep, she had definitely gone insane.
They arrived at the vet clinic and knocked on the door. Luckily, Deaton was still there and opened the door.
"Melissa?" he asked.
"Hey. This girl came to my house saying she was drawn to it. It seemed like something in your area of expertise. He motioned for them to follow him to the back room. He closed the half-door before Becca could get through. Confused, Becca went to open the gate, but was pushed back by an invisible force. Mountain ash.
When she was pushed back, her eyes flashed purple. Upon seeing this, Deaton opened the gate for her and she hesitantly stepped through.
"Purple? I didn't know that was a thing. What does that mean?" Melissa asked Deaton.
"It means she is a special kind of wolf. An epsilon wolf," Deaton answered.
"I'm sorry, a wolf?" Becca asked frantically.
"Sit tight, I'll explain everything to you in a minute," Deaton said to Becca. Then he turned to Melissa.
"An epsilon wolf is the guardian of the pack. It's job is to keep the other pack members safe. But Becca is a rare form of it. She is a human as of right now, but has been slowly gaining power ever since Scott became the true alpha. She is destined to be part of his pack. That's why she was drawn to your house." he continued.
"I came here because strange things were happening to me back in New Jersey. My cousin, Jordan Parrish said he knew people who could help me, so I moved here. Are you those people?" Becca asked quietly.
Deaton nodded and said, "You'll like Scott, he's the best alpha I have ever seen. He… cares. Melissa you need to call him and tell him to get down here as fast as he can. I know he's on a camping trip, but this is important. In order for Becca to fully become a wolf Scott needs to assert his dominance over her."
"And he can do that by…?" Melissa questioned.
"Biting or scratching her," Deaton said.
"Excuse me?!" Becca yelled.
"Every full moon you go without changing, the human part of you weakens. After 3 your human form becomes too weak and you don't the full power of a werewolf, so you'll…" Deaton paused.
"Die!" Becca finished the sentence for him. "How many full moons have there been?" she asked.
"2, since Scott became an alpha."
"When is the next one?"
"Tomorrow night."
Becca started hyperventilating. This was too much. She quickly ran out of the room and burst through the doors to get fresh air. She collapsed onto her knees in the parking lot. Holding her head in her hands. Melissa followed her and sat behind her, placing a hand on her back. Becca's breathing slowly steadied herself.
"I am going to call Scott, okay? He'll be able to fix all of this, it's kind of his thing," Melissa said softly, comforting her. Becca only nodded in response as Melissa quickly called Scott. It went to voicemail (he was currently at the abandoned church).
"Hey! Scott, it's your mom. So, uh, I met this girl and turns out she's half supernatural, it's kind of a long story, but if you don't get down here before tomorrow night, she's going to die, so hurry up." Melissa tried to sound calm on the phone, but she was scared for the girl.
Becca sat in the parking lot, trembling. She had no idea who this Scott was, but there was no one she wanted to be with more right now.
Okay so just as a reference I planned it out as this was happening on Saturday night. Scott arrived in Mexico on Friday and him and his friends got captured at the club Friday night. The next day (Saturday) they were sent to the abandoned church and they didn't arrive until Saturday night. Then, they leave in the middle of Saturday night/super early Sunday morning.
