Castiel had one simple question. That was it. He didn't expect to spend the whole night with the Winchesters and a mystery hunter. Cas had found a german shepard puppy on the side of a rainy street in New York. Castiel found New York one of the best places for people watching. That small, shivering puppy was curled up in a damp cardboard box. "Please take me home" was written in running letters on a flap of the box. Castiel couldn't resist.
"Hello Dean." Castiel said drenched in rain, holding an equally as drenched puppy in his arms. When he had arrived at the base there was a strange, scrangly, man sitting across from Dean, both were slightly pink. "Dean, I found this puppy and we should keep him." Cas held the dog at arm's length, waking it up. It looked around, confused.
"Cas!" Dean seemed strangely relieved. He rushed over to the dripping angel and flung his arm around his shoulders. He quickly removed his arm when he felt the rain soak through his sleeve. "Uh, why do you have a dog?" He hastened Cas' response.
"Um, I just told you Dean." Castiel looked around for any social cues that would get him out of the current situation. He saw a small man staring at his new canine companion, Dean eager with a hint of mortified, and no Moose in sight. "May we keep this dog?" He held the puzzled puppy up to Dean's face, hoping that the small animal would snap him in to reality again.
"Um, yeah, sure. Listen! This is Garth! My, uh, friend! Yeah." Dean was definitely uneasy. Castiel put Dean's symptoms through all tests of illness he could think of. What if it was... oh.
"OH." Cas gasped after about ten seconds of silence. He smiled in a way he found friendly. Apparently Garth did not. He turned and gave Dean an exaggerated wink and thumbs up then strode into the kitchen to talk to Sam.
