Sam wonders how Percy stay alive and fine for experiencing those things.

He can manage to smile despite the loss he had for a few years.

He managed to have fun despite his desperation to survive.

Despite the struggles they face, he can still manage to do anything he wants.

Percy stood up from his seat. "The hunters are asleep now, Thals. We need to go now. Lady Artemis might get mad to see boys with her hunt."

Phoebe nodded. "We'll take care of them. Be careful on your way."

"Thanks, Phoebe." Percy smiled. "Guys, hold on to me."

As soon as the brothers touched his shoulders, they disappeared.

Or shall we say they saw nothing.

Next thing the brothers knew, they're facing the Impala. Both of them kneeled to the ground, feeling like a liquid that solidified but still squishy. Percy snickered.

"Sorry about that." He said. "It's one of my skills. Vapor travel."

"Holy shit. I don't know if Cas's teleport or yours is the worse." Dean said.

"Don't worry, that would be the last. That's the first time I did it with a company. And it's tiring." Percy said.

Sure enough, the said teen is pale. He almost stumbled from his position if Dean didn't steady him. "Whoa there, kiddo. If that's exhausting, you shouldn't be doing that."

"Bring me to Caldecott tunnel. I'll be fine after that." Then Percy slept.

Percy already passed out, so Dean put him at the backseat carefully and stared at the teen. Sam was happy that it was done. Those whole month of chasing a lycan was exhausting, but the result was good, and they learned so much from the teen.

Both of them sat at the shotgun and driver's seat. "So, what now?"

Dean answered. "Let's take a nap for now. Tomorrow, we'll bring the kid to that tunnel wherever the hell is that. We need to sleep. All of us."

Dean being fine, he drove to the nearest motel to crash for the night before they head to a journey, while Sam is trying to look where the Caldecott tunnel is.

After a few clicks, Sam found that it was near to their location with just a few turns, so it won't take almost half a day to scale the while California for the tunnel.

Out of curiosity, Sam scanned the things inside Percy's bag to kill some time since sleep doesn't come to him despite the exhaustion from the battle they have. Regardless, Percy was more exhausted as he did most of the work, strategy and protecting them.

He noticed that the bag contains the essential things that a traveler has: clothes, food, water container, first aid, hygiene kit, and some weird looking coins and dollars. No more, no less. It seems like he's used being on the run always when trouble happens.

Sam decided to put something inside the bag as a remembrance to Percy.
