Castiel sighed as he sat down in the stands. It was required for everyone to watch the "games" so he was in attendance. Sam was preparing to fight his ghoul, broad sword in hand. Dean came over and sat next to Castiel. His face looked drawn and worried and pale and exhausted. He didn't say a word to Castiel as he pushed his hand into the other professor's. Castiel was uncomfortable at the painfully tight grip but allowed it. Ruby had defeated the pixies easily using Bombada maxima to obliterate them all in one swift motion and Crowley had used a water curse to bring his phoenix down. Now it was Sam's turn. As it started Dean clutched even tighter to Castiel's hand. He was starting to feel pain but he ignored it, focused more on Sam. Dean walked out into the graveyard and Castiel waited for Sam to falter. He looked at the creature and charged at it. Not expecting such a brash move, it sidestepped, just out of range of the blade. Castiel turned to Dean, going to ask but he looked too worked so Castiel dropped it for later questioning. Sam charged again, this time, cleaving the sword in the top of the ghoul's head. The creature took no notice and Castiel felt annoyance and anger rise in him. He had told Sam to cut off the head. The creature took a moment to pull the sword from its head but by the time it had returned its attention to Sam, the kid had sliced off its head with a second sword. Clever, Castiel though. He had used a splitting sword, one that could be split in half or used together as one. It had the appearance of one when the two halves were out together so, when split, it give the target something to distract them as the final blow was dealt. Sam turned to the crowd triumphant. Castiel looked at Dean to see his sagging shoulders lift, his pale and strained face regain its normal look and a grin make its way across his face. Dean raced down to where Sam was walking out of the graveyard, shoving through the crowd and dragging Castiel behind him. He'd probably forgotten he was holding his hand but his grip was unrelenting so Castiel just trailed after him. They reached Sam who was getting cheers and pats on the back. Dean brushed them all aside to hug his brother, at last letting go of Castiel's hand. When Dean stepped back he turned to Castiel. He was either going to introduce him or drag him off somewhere and Castiel, keen on neither, began to regret not escaping while they were hugging.
"Dean." Sam said pointing to Castiel. "This is the guy. The one who told me what to do." Sam said enveloping Castiel into a hug. Not being used to hugs, Castiel just stood there awkwardly. Soon Sam was pulled away by the crowd laughing and cheering. Dean was staring at him.
"You let the ghoul bite you?" Castiel asked wondering where the bite mark was. There were only two people who could fix it before it got infected: Castiel and the school nurse. The nurse must have been in on it but Castiel wanted to check it out just in case. Suddenly Dean's arms were around his neck and his mouth was on his. Castiel mewled in surprise but was already melting into the kiss. Dean's tongue darted into Castiel's mouth, not asking permission but forcing its way in, not that Castiel was fighting. When Dean pulled back Castiel was seeing stars dance around his vision. It took all the limited brain power he had left to remain standing.
"Thank you for helping my baby brother." Dean said before hurrying off after the procession carrying Sam. Castiel stood there for a moment, trying to get his thoughts back in order. When he was finally coherent and back together, he stood up, straightened his robes and went off to take care of the Puffskeins he was keeping for their next class.
