"Hey, Cas-"

"Yes, (Y/N)?" His blue eyes flicker from the small yellow object, to you, and back to the object. His chin resting on his crossed arms, glaring at it.

"What are you, and why are you so yellow? Why don't you blink? Is this your purpose in life, just sit there and stare at me?" He pouted and continued the staring competition.

You chuckled leaning on a chair across from the curious angel.

"Why are you laughing, (Y/N)?" He looks up at you and tilts his head to the right.

"The question is: why are you having a stare-down with a rubber duck?" You say, laughing softly again.

"I found this in the library," he said pushing it away from him. "And these..." He opened his trench coat only for, about, a dozen ducks to fall out. "In my trench coat and shoes. What is going on (Y/N)? Why are there ducks everywhere?" Castiel walked up to you and stood there until you controlled your laughing.

"(Y/N), this is a serious matter. these rubber ducks are everywhere." His eyes stare into yours; horror was present in them.

"They're just toys, Cas," you say, picking one up. "The Winchesters probably have something to do with this."

He looks at the duck, then at you, to the pile of ducks, then back at you. He scrunched his face in confusion, "what are these ducks for?"

"Well, kids put these in the bath when they bathe. It's just a bath toy," you say, placing one on his head.

"I don't know why father created these for such purpose." He grabs the duck from his head and places it inside his trench coat; along with the few dozen askew on the floor.

"What in your father's name are you doing, Cas?"

"Something..." He picks up the last one and runs to the bathroom, slamming the door shut and doing whatever the hell he's doing in there. You glance up as his head pops out of the bathroom door,

"Wait there," he says and closes the door once more.

"Okay then..."

.:5 minute timeskip:.

After a while, a weird, muffled, noise can be heard resonating from the bathroom. You decide to get up, 'what the heck, why not?' and walk over to the door. The noise gets louder and then you can hear it clearly, the sound of quaking can be heard from the other side of the door.

"Cas? I'm coming in," you say afraid of what's on the other side.

You twist the doorknob and push open the door to see Cas squatting next to the bath tub.

"Aren't these better than the plastic ones?" He asks, turning his head around to meet your glance. You tilt your head 'better than the plastic ones?'

"What are you- oh. Cas! These are adorable!" You smile and crouch next to him to pick up a small duck who had been paddling in the tub. The small duck stared at you in amazement and quacked.

"It says you're cute," Cas looks at you and smile.

"Come on, Cas, we know it didn't say that-"

"You're right, I said it," he picks up another duck and places it next to your cheek, mimicking a kiss.

"Aww, thank you, Cas." You leaned in an pecked his cheek. The small ducks began to ruffle their feathers together and laid cuddled to each other. Both Cas and you began to laugh and continued to play with the ducklings, planning the revenge prank on the Winchesters.
