It took awhile for Cas to find Sam and Dean. He knew they would go back to the bunker; he had heard of it, but he didn't know exactly where it was. He couldn't fly anymore, so he walked to the nearest restaurant to ask if he could borrow their phone.
"Thank God, Cas," Dean said.
"I saw the sky," Cas said. "I caused this, didn't I?"
"You didn't know," Dean said. "You didn't know he was going to do this."
"But I didn't want to believe Naomi," Cas said.
"That doesn't matter," Dean said. "Sam didn't finish the trials, and he's still dog sick."
Cas stared at the wall. "We're going to have to find Him, aren't we?" he asked.
"Yes," Dean said. "He's the only one who can heal Sammy and kick Metatron's ass."
"Where are you?" Cas asked next.
"At the bunker," Dean said. "You don't have your wings, do you?"
"No," Cas answered with a sigh.
"Okay," Dean said. "I slipped a credit card into your coat, Cas, just in case this happened. In one of your waist pockets, I want you to take a bus here. Ask for directions if you have to, and you get food if you need to as well."
Cas slipped his hands into his pocket and came out with a MasterCard credit card with the name Devin Hetfield. "Thank you, Dean," Cas said.
"Don't thank me, yet, Cas," Dean said. "All hands are on deck until we find God and deal with Metatron." Dean hung up.
Cas hung up then. He looked at the bartender. "Can you tell me where the closest bus station is?" he asked.
