Gabriel disappeared but that was just in time for Dean to tackle Secret. He covered Secret's mouth and and slit his arm, drinking the blood. Secret brought his knees up to his chest, placed his feet on Dean's chest and shoved him off. He stood up quickly and took several steps away from the rather pissed off Dean.

Just then, Sam came running over and Cas appeared. Sam grabbed Dean before he could say anything and cuffed him.
"You filth, get your hands off of me!" Dean shouted.
"No can do. " Sam said and started leading him back to the motel. Good thing this wasn't a very popular place.

Sam cuffed Dean to the bedpost and sat down with a huff. Cas appeared seconds later. Secret trudged in, pulling sticks out of his white hair.
"I need a shower." He said and he did just that. Once he got out he borrowed some pj pants and a t-shirt from the boys while Sam took Secret's clothes to the laundromat. The clothes were way too big on him so he just decided to not move and watch some T.V. Cas was there too but he didn't really say anything. He just stood there. Watching. That wasn't unsettling at all.

Sam got back with Secret's clothes eventually and when Secret put them on he declared this was his heaven. He had always washed his clothes in a river or something and hung them out to dry. This time his clothes were soft, warm and smelled like daisies. He kinda just snuggled himself for 15 minutes straight.

"Okay," Secret said after he finally stopped nuzzling his clothes, "It's Gabriel. He's the one talking to Dean and convincing him to do stuff." Cas and Sam looked at Dean.
"Is this true, Dean?" Cas said. Dean said nothing.
"Oh, it's true, alright. I'd know tha-" Secret suddenly burst into a fit of coughing. He shook his head and continued, *"Watashi wa him - eh??
Nani? Watashi wa
Nihongo o hanasu Imu?! Nantekotta?!?!"
"Woah, woah, what??" Sam said.
"He's speaking Japanese." Cas said.
"Un, Soshite, watashi wa teishi suru koto ga dekinaku narimasu!!!" Secret said.
"What did he say?" Sam asked.
"He said he can't stop." Cas said.
"Don'nani isshōkenmei yatte mite!"
"No matter how hard he tries."
"Well this is just great." Sam said.
"Kore wa gaburieru' a shite inakereba narimasen!" Secret said.
"He says that this must be Gabriel's doing." Cas said. Sam sighed.
