It was Stiles who realized what was going on.

His work as an FBI agent and his connections with other paranormal enthusiasts led him to it. A case of an unidentified, charred, and buried body in the middle of nowhere. The victim was a woman in her late 30s, according to the tests. Rowan wood residue and dog parts were discovered among her remains. Stiles started looking into it, and soon he had plenty of cases that seemed connected.
There were no more dog bones, but there was rowan wood with burned bodies. Even when the tree did not naturally grow in the area. With all of this, Stiles confidently believed that the victims were either werewolves or some other kind of supernatural entity. The recent murders had spread throughout Canada, as far as Stiles could tell.

Upon receiving all this information back at Beacon Hills, Scott's pack suspected that it might be connected to Monroe. Just like many other strange cases they have noticed lately. The woman's name has begun to surface in the paranormal world across America and beyond. Supernatural people being targeted and hunted, despite the fact that the majority of them are peaceful individuals. Even Isaac had sent an email from France, saying that hunters were causing unrest among the werewolf population there.

It has been around two years since Monroe's army of hunters tried to exterminate the supernatural residents of Beacon Hills. She seems to want to give it another go, but on a larger scale.

Beacon Hills, central California.

Peter Hale threw last of his bags into his car and adjusted his shades as the sun peeked through the clouds. It was still morning. With everything he needed, he closed the trunk.

"Hey."
When the man saw Malia, his biological daughter, he was genuinely taken aback. Although he didn't show it. "Derek said you were leaving?" the girl asked while crossing her arms. "Just a small getaway," Peter shrugged while leaning onto his car. "Thought about finally getting a break from all the supernatural teen drama over here."
The young woman snorted. She was... Kinda glad he wasn't dumping them for good. He still was her father, though not sure did it mean anything to him but she just... Their relationship wasn't simple one. But truthfully, she was relieved he wasn't leaving. Although they didn't spend much time together. Peter sensed her relief and it made him a slightly giddy. Knowing that, seemingly, someone would miss him was welcoming. Everyone else, who mattered, didn't shy away from expressing their desire to have Peter leave the town. That's unfortunate, though, since he would return like always. It's one of his bad habits.
Unsure should she leave now or not, Malia kept asking: "Where you going then?"
"Ah, hard question," the man pondered. "Maybe somewhere far away, that's for sure. Not Mexico, though. Nice beaches but I have enough of the local wildlife."

Peter chuckled and parted his lips, remembering something from his childhood. But he covered his mouth with a false cough. Keeping himself from being overly sentimental with the girl. All of that, that family life, was in the distant past. Or, more accurately, in one of his past lives.
Also, he didn't think the girl was interested in learning about some unknown relatives. She has never asked about them, and despite knowing her origins, she continued to use her adoptive family's surname and lived with Henry. Clearly, she had no desire to be a member of the Hale family.
After an awkward moment, Peter wondered about her desire to become a mechanic. It was just something he had overheard during pack meetings. Malia admitted that she had developed an interest in car repair because she and her dad had done it frequently. Peter nodded and asked about her studies regarding that career path. The whole conversation was oddly normal, so Peter cut it short.

"Mind doing me a favor, sweetheart?"
"What kind?" She was suspicious right away. That soured Peter's mind a bit. Oh well.
From his trench coat, he pulled out some car keys. "Could you take care of one of my cars? This one needs some attention from a promising future mechanic to stay in fine condition." Before she could respond, he tossed the keys, and she took a quick look at them. He had attempted to gift her another car in the past, but Malia had turned it down. Good, because there had been a serious malfunction in that car that caused it to blow up. But this time, she gave a slight smile and nodded before putting the keys in her pants pocket. "I guess. Does it mean you have to give me one?"
"That's the way favors work," he smirked. He only hoped she wouldn't use this favor for the pack later on. Hopefully she would ask something small, like a brand new toolkit or a high end laptop.

They then haphazardly said their goodbyes, with Peter getting into his car. As he drove away, he glanced in the rearview mirror to see that Malia was already walking in the other direction. He speeded up a bit.

Soon, Peter was out of the town, driving barely within the speed limits and playing his favorite songs from the radio. The windows were open, allowing him to enjoy a cool breeze on his short hair.

He was not taking a vacation, nor was he leaving the country. He knew the others would not have accepted his offer to do this. Most likely wouldn't have allowed him to go at all. The truth is that the pack and town are lagging in... Every way, if they intend to keep fighting Monroe's army. Not only in town, but also across the country, as Scott had been suggesting. After everything that had happened, the boy was the center of attention. His accomplishments and his status as the chosen alpha had reached the ears of all supernatural beings and hunters. Beacon Hills was rising to prominence once more. It implied that more problems would arise, particularly in light of Monroe's and her people's actions.
Thus, Scott's pack would require assistance. It was understandable that Derek was hesitant to connect with other families, even with those of the Hales. Before long, hunters, shapeshifters, and other packs would begin to consider attempting to seize control of Beacon Hills. That's what Peter would do. Asking for help and displaying weaknesses now was a risk. However, Peter believed it would be preferable if they recruited real packs to bolster their numbers rather than having Scott simply collect any stray off the streets.

Peter had to handle this his way. Scott was still a kid, and Derek? Derek wasn't trained to be an alpha. Nephew's past actions proved that... So Peter needs to make some plans and strike some deals. Make sure that Beacon Hills gets assistance when needed without becoming a target.

The relatives in Idaho would be his first target. He already knew a few of those folks and had information on them. There may be something he can use to secure an alliance. Peter grinned with delight. This would be fun.

West Quebec, Canada.

An old, worn-out RV was parked in a mostly empty caravan area. The lights were on, and the owner smoked while sitting in the trailer's doorway. A group of dogs next to the man raised their heads when an unknown car pulled up. He didn't seem suspicious of the approaching strangers, so his pets settled back down. A dark-skinned woman with two men approached. The RV owner threw away his half-burned cigarette. "You Monroe?"
"Yes. Have you given my offer any thought?"
Stretching his back, the man stood up. "Working for you? Yeah. Honestly, I think you can't afford me."

She glared at that response, clearly not liking it. "This is not just a job, you know. What we are doing is far-"
The man gave a whistle. His hunting dogs stood up, and a wolf appeared out of the RV. The strangers pulled out their weapons, and the large wolf snarled, followed by the other canines.
"Platz." The canines lay down quietly.
"Puppe. Komm rein." The wolf got up and returned inside the RV. The owner gave Monroe a sly smile. "I'm a hunter, miss. But me and my pets need to eat. And my services are worth every penny." Following that brief demonstration, a deal was discussed and agreed upon. After Monroe and her men left, the hunter stepped inside the trailer.

Finding the wolf sitting near the door, he chuckled and grasped the animal by its cheeks. "We got a job, girl." he spoke in German. "We're gonna get hunting."
With excitement, the animal began panting and wagging its tail.
