It was a metal bird, he's heard of these metal birds before. Maybe they have the secret that can allow him to fly. He went to the thunderpath and watched for a specific monster going eastbound.
Eventually one came into his view, it was a giant behemoth that was hauling a larger metallic box. He jumped on top of the box and rode the monster for a long while.
Eventually the runway of the airport was in sight, he was way out of the forest at this point. So he jumped and glided to the metal fence around the outside of the airport. He couldn't get closer and didn't want to. He watched the next plane take off carefully. Fast, constant, slow rise. Blackwing mentally noted it. Went back over to the road to wait for a westbound semi truck. One came and he hopped on to get back to the forest.
Returning to the forest he hoped off the monster's metal box and walked back to his treehouse Bunnystep was sitting at the balcony waiting for him, "Bunnystep? Why are you here?" Blackwing asked his friend.
"O-Oh I'm here because something happened in the camp." Bunnystep vaguely explained. "What happened Bunny?" Blackwing asked, "This has to be something big to warrent getting me-" Blackwing was interupted by Bunnystep, "Two cats died last night."
Blackwing was shocked, how did this happen? "The leader told me to get you, since he knows that I knew where you are." Bunnystep explained better, "He said that 'an assassin would know how to track a killer down', I don't know why he would risk it."
"So, are the bodies still near the thunderpath?" Blackwing asked, Bunnystep shook her head. "They were moved? Where?"
"Blackwing, where else would warriors take a fellow clanmate's body?" Bunnystep said. Blackwing facepalmed as he realized his dumb question.
They arrived at the camp, the bodies were surrounded by the senior warriors as well as the leader, deputy and medicine cat. As Blackwing approached the bodies, the senior warriors cleared space for Blackwing so he could see the bodies clearly. "Who are these?" Blackwing asked, hoping for something to work with. The leader turned to Blackwing, "Cocoapaw and Abysssight." The leader said, Blackwing was looking closer to try to tell what killed them. Cocoapaw has rope burns around his torso and a slit in his throat and Abysssight had a claw mark across her whole face, and a mark indicating suffocation. "I know this tactic well. Assassins and killers I've talked to call it a '2 for 1' where with one, you bring another one in." Blackwing explained, "Look, Cocoapaw was held by a trap, and with another cat nearby coming close enough..."
"They could kill both in a short amount of time." One of the senior warriors interjected. "Exactly. So I'd say get a patrol out to find the traps, and disarm all but one." Blackwing said, the leader looked at Blackwing confused. "If one of the traps is still active, I could rig it to get our cat." Blackwing explained.
The leader nodded with understanding, "I understand, Do you want to go with the Deputy and go along with the patrol?" Asked the leader, "Yeah." Blackwing responded, "and you can go through with buring the cats now, I don't need to look anymore at them now."
He was sitting in a trap, waiting for the killer to get there. Then he heard them approaching, their pawsteps slowly getting closer. A little longer. Blackwing thought, then he felt the cat on top of him and he backflipped out of the trap, ripping it apart. And there was the killer. Laying on their side, stunned from Blackwing's quick defense. Blackwing walked over and extended his claws.
